As part of her custody case, Jeremy Renner's ex-wife Sonni Pacheco has filed serious claims against the Avengers: Endgame star.

In her filing, Pacheco alleges Renner threatened to kill her, put a gun in his mouth and shot it at the ceiling while their six-year-old daughter Ava was in her room, People reports. She also cited drug use, including incidents where Renner left cocaine within their daughter's reach.

“The well-being of his daughter Ava has always been and continues to be the primary focus for Jeremy,” Renner's lawyer said in a statement. “This is a matter for the court to decide. It’s important to note the dramatizations made in Sonni’s declaration are a one-sided account made with a specific goal in mind.” He called the allegations "one-sided."

Pacheco, who wed Renner in 2014, filed for divorce after less than a year of marriage, with an agreement to share custody of their child. She is now seeking sole custody of their daughter, with monitored visitation whenever Renner is with her. A court date is set for November 7.

Renner shot to stardom thanks, in part, to his role as Clint Barton, aka Hawkeye, in the Marvel Cinematic Universe. He has appeared in Thor, The Avengers, Avengers: Age of Ultron, Captain America: Civil War and Avengers: Endgame. He was announced to return for Hawkeye, slated to debut on Disney+ in 2021, but it is unclear at the time of writing if this case will impact his future in the MCU.
