The carbon fiber hull of the experimental submersible that imploded en route to the wreckage of the Titanic had imperfections dating to the manufacturing process and behaved differently after a loud bang was heard on one of the dives the year before the tragedy, an engineer with the National Transportation Safety Board said Wednesday.

Engineer Don Kramer told a Coast Guard panel there were wrinkles, porosity and voids in the carbon fiber used for the pressure hull of the Titan submersible. Two different types of sensors on Titan recorded the “loud acoustic event” that earlier witnesses testified about hearing on a dive on July 15, 2022, he said.

Hull pieces recovered after the tragedy showed substantial delamination of the layers of carbon fiber, which were bonded to create the hull of the experimental submersible, he said.

OceanGate co-founder Stockton Rush was among the five people who died when the submersible imploded in June 2023.

Kramer’s statements were followed by testimony from William Kohnen, a longtime submersibles expert and key members of the Marine Technology Society. Kohnen emerged as a critic of OceanGate in the aftermath of the implosion and has described the disaster as preventable.

On Wednesday, he pushed back at the idea the Titan could not have been thoroughly tested before use because of its experimental nature.

“We do have these test procedures. They are enshrined in law,” Kohnen said.

The Coast Guard opened a public hearing earlier this month that is part of a high level investigation into the cause of the implosion. Some of the testimony has focused on the submersible’s carbon fiber construction, which was unusual. Other testimony focused on the troubled nature of the company.

Coast Guard officials noted at the start of the hearing that the submersible had not been independently reviewed, as is standard practice. That and Titan’s unusual design subjected it to scrutiny in the undersea exploration community.

Earlier in the hearing, former OceanGate operations director David Lochridge said he frequently clashed with Rush and felt the company was committed only to making money.

Lochridge and other previous witnesses painted a picture of a company that was impatient to get its unconventionally designed craft into the water. The accident set off a worldwide debate about the future of private undersea exploration.

The hearing is expected to run through Friday and include several more witnesses, some of whom were closely connected to the company.

The co-founder of the company told the Coast Guard panel Monday that he hoped a silver lining of the disaster is that it will inspire a renewed interest in exploration, including the deepest waters of the world’s oceans. Businessman Guillermo Sohnlein, who helped found OceanGate with Rush, ultimately left the company before the Titan disaster.

OceanGate, based in Washington state, suspended its operations after the implosion. The company has no full-time employees currently, but has been represented by an attorney during the hearing.

During the submersible’s final dive on June 18, 2023, the crew lost contact after an exchange of texts about Titan’s depth and weight as it descended. The support ship Polar Prince then sent repeated messages asking if Titan could still see the ship on its onboard display.

One of the last messages from Titan’s crew to Polar Prince before the submersible imploded stated, “all good here,” according to a visual re-creation presented earlier in the hearing.

When the submersible was reported overdue, rescuers rushed ships, planes and other equipment to an area about 435 miles (700 kilometers) south of St. John’s, Newfoundland. Wreckage of the Titan was subsequently found on the ocean floor about 330 yards (300 meters) off the bow of the Titanic, Coast Guard officials said. No one on board survived.

LOS ANGELES (AP) — Another woman sued Sean “Diddy” Combs on Tuesday, alleging that the music mogul and his head of security raped her and recorded it on video at his New York recording studio in 2001.

The lawsuit filed in federal court in New York, the latest of several similar suits against Combs, comes a week after he was was arrested and a federal sex trafficking indictment against him was unsealed.

Thalia Graves alleges that when she was 25 and dating an executive who worked for Combs in the summer of 2001, Combs and Joseph Sherman lured her to a meeting at Bad Boy Recording Studios. She said they picked her up in an SUV and during the ride gave her a drink “likely laced with a drug.”

According to the lawsuit, Graves lost consciousness and awoke to find herself bound inside Combs’ office and lounge at the studio. The two men raped her, slapped her, slammed her head against a pool table and ignored her screams and cries for help, the lawsuit alleges.

At a news conference in Los Angeles with one of her attorneys, Gloria Allred, Graves said she has suffered from “flashbacks, nightmares and intrusive thoughts” in the years since.

“It has been hard for me to trust others to form healthy relationships or even feel safe in my own skin,” Graves said, crying as she read from a statement.

She said it is “a pain that reaches into your very core of who you are and leaves emotional scars that may never fully heal.”

Combs remains jailed without bail in New York on federal charges alleging that he ran a vast network that facilitated sexual crimes and committed shocking acts of violence, using blackmail and other tactics to protect Combs and those close to him.

He pleaded not guilty to racketeering conspiracy and sex trafficking. His attorney said he is innocent and will fight to clear his name. His representatives did not immediately respond to an email seeking comment on the latest lawsuit. There was no immediate indication from the lawsuit or from Combs’ representatives whether Sherman had a separate attorney who could comment on the allegations.

Graves’ lawsuit also alleges that late last year, after Combs’ former singing protege and girlfriend Cassie filed a lawsuit that began the surge of allegations against him, Graves learned through her former boyfriend that Combs had recorded her rape, shown it to others and sold it as pornography.

The Associated Press does not typically name people who say they have been sexually abused, unless they come forward publicly as Graves and Cassie, whose legal name is Casandra Ventura, have done.

Graves’ lawsuit says both Combs and Sherman contacted her multiple times in the years after the assault, threatening repercussions if she told anyone what had happened to her. She was in a divorce and custody fight at the time and feared losing her young son if she revealed anything, the suit says.

Graves said at the news conference that the guilt and shame attached “often made me feel worthless, isolated and sometimes responsible for what happened to me.”

The lawsuit seeks damages to be determined at trial and for all copies of the video to be accounted for and destroyed.

It also names as defendants several companies owned by Combs, the three-time Grammy winner and founder of Bad Boy Records who was among the most influential hip-hop producers and executives of the past three decades.

But mystery readers are really in for a treat. There has been a bumper crop of whodunits, thrillers, and crime novels for those who prefer to read on the edge of their seat. And the year’s not over yet — high-profile books from crime fiction titans Michael Connelly, Attica Locke, Richard Price, and Paula Hawkins are all on the horizon.

We’ve collected 20 promising books covering all types of mysteries and thrillers — some out now, some coming soon. If you’re looking for an engrossing read that might just scare you a little, check these out — just remember to lock your door if you’re reading at night.

Preston and Child have collaborated on more than 30 books ever since their debut novel, “Relic,” was published in 1995. Their latest sees the return of their popular character Aloysius Pendergast, an FBI agent who this time is on the trail of a New York serial killer — who happens to be Pendergast’s ancestor.

Scott Phillips, “The Devil Raises His Own”

Phillips is best known for his historical noir fiction set in the American West, and his latest novel finds him training his eye on the Silent Era of Hollywood. The book follows an L.A. photographer in 1916 who finds himself entangled in the nascent porn industry; a series of murders complicates his life as well as that of his granddaughter, who has moved to the city from Kansas after killing her abusive husband.

Seishi Yokomizo, translated by Bryan Karetnyk, “The Little Sparrow Murders”

The British publisher Pushkin Press puts out some of the highest-quality crime fiction under its Pushkin Vertigo imprint.

Hansen Shi, “The Expat”

Readers who love a good spy novel might want to reach for this one by venture capitalist Shi — it follows Michael Wang, a young Princeton graduate working a tech job at General Motors, who is headhunted by Vivian, a woman who invites him to come work in China. When Michael travels to Beijing, Vivian is nowhere to be found, and he realizes he might be entangled in something much bigger than he bargained for.

M.T. Anderson, “Nicked”

Anderson is best known for his novels for younger readers (“Feed,” “The Astonishing Life of Octavian Nothing, Traitor to the Nation, Volume I: The Pox Party”), but he has a grown-up audience in mind for this one. His latest book is a heist story, set in the 11th century and follows Nicephorus, a naive Italian monk who is talked into joining a plot to steal the bones of St. Nicholas.

P.J. Tracy, “City of Secrets”

German author Swann brings the cozy in this follow-up to her mystery novel “The Sunset Years of Agnes Sharp.” This one sees the return of the titular woman and her fellow elderly housemates as they attempt to solve a possible murder in a fancy Cornwall hotel.

Kate Atkinson, “Death at the Sign of the Rook”

Literary novelist Atkinson is hard to pin down when it comes to genre, but her books featuring detective Jackson Brodie are unabashedly mysteries — and undeniably fun. In her latest, something of an homage to Agatha Christie, Brodie uncovers a series of art thefts in Yorkshire that leads him to something even more sinister.  

Kwei Quartey, “The Whitewashed Tombs”

Emma Djan, the Ghanaian private investigator featured in three of Quartey’s previous novels, returns in his latest. This time, she’s investigating the murder of an LGBTQ+ activist in Accra; her investigation leads her to a group that is trying to make homosexuality illegal in several African countries.

Richard Osman, “We Solve Murders”

British author Osman scored a series of bestsellers with his cozy “Thursday Murder Club” series of novels (the first of which is headed to the big screen, courtesy of Steven Spielberg). He’s kicking off a new series with this novel, about a retired detective who works with his security officer daughter-in-law after she learns that she’s been targeted for murder.

Readers who enjoy a little paranormal mixed in with their mysteries should take a look at this novel, which follows a small-town librarian who realizes that a string of murders in her village might be the result of something demonic. (The possession of her cat, Lord Thomas Crowell, also clues her into the malevolent spirits.) She enlists a priest and a group of townspeople to investigate what’s really going on

Marissa Stapley, “The Lightning Bottles” (Sept. 24)

The latest from “The Last Resort” and “Lucky” author takes readers back to the 1990s grunge era. The novel follows Jane Pyre, who founded the titular band with her then partner Elijah Hart, who has since disappeared. Jane moves to Germany, where a teenage fan insists that Elijah is still alive and waiting to be found. Mystery fans who also love Taylor Jenkins Reid’s “Daisy Jones & the Six” will find much to admire here.

Ramona Emerson, “Exposure” (Oct. 1)

Emerson was longlisted for the National Book Award for her debut “Shutter,” which introduced readers to the New Mexico forensic photographer Rita Todacheene. In this follow-up, Rita is called in to help with the investigation of a serial killer who is targeting Native victims in the city of Gallup.

Lauren Ling Brown, “Society of Lies” (Oct. 1)

Brown, a film editor living in L.A., makes her literary debut with this suspense novel about Maya, who returns to her alma mater of Princeton to see Naomi, her little sister, graduate.

Sarah Sawyer, “The Undercurrent” (Oct. 8)

In Sawyer’s debut novel, a Maine woman named Bee is trying to navigate her postpartum depression when a childhood friend makes a reappearance and leads her to travel back to her Texas home, where she becomes obsessed with the disappearance of a girl from her town. “Gone Girl” author Gillian Flynn calls this one “stunning.”

Delilah S. Dawson, “It Will Only Hurt for a Moment” (Oct. 22)

Arriving just in time for Halloween — yes, spooky season is coming soon — Dawson’s novel follows Sarah Carpenter, a woman who leaves behind her ex-boyfriend and mother to make pottery at an artists’ colony. Things get dicey when she discovers a body of a young woman, and her fellow artists start acting unusually.

Sydney Graves, “The Arizona Triangle” (Oct. 22)

Tod Goldberg, editor, “Eight Very Bad Nights: A Collection of Hanukkah Noir” (Oct. 29)

Indio-based author Goldberg is one of the best (and funniest) crime writers working today, so it makes sense that publisher Soho put him in charge of this Hanukkah-themed short story anthology. Contributors include authors Ivy Pochoda, David L. Ulin, Jim Ruland, Gabino Iglesias, Liska Jacobs and Goldberg’s novelist brother Lee, all of whom are likely to serve up thrills alongside your latkes.

Christina Lynch, “Pony Confidential” (Nov. 5)

Champing at the bit for a mystery with an equine hero? Look no further than the latest from College of the Sequoias professor Lynch, which tells the story of a pony determined to prove that her old (human) friend Penny didn’t commit a murder that she’s been accused of. With Penny languishing in jail, Pony can’t afford to horse around.
