Tommy Lee Jones is reportedly keeping a "low profile" while he grieves the death of his daughter Victoria Jones

A source told People: "[He] has continued to keep a low profile. He's very private and mostly keeps to himself. He only leaves his ranch occasionally for necessary errands. He's a lifelong Texan at heart.

"He's focused on cattle ranching and polo. He still rides, though less frequently.

"While his work kept him in the public eye for decades, he was never comfortable with the attention. His life now gives him great privacy."

In a statement, the San Francisco Fire Department told Us Weekly following Victoria's death: "Upon arrival, paramedics from the fire department performed an assessment. The person was dec lared deceased.

"SFPD and the medical examiner's office were called to the scene. Scene turned over to SFPD and SF Medical Examiners."

A 911 call revealed that San Francisco police officers received a call for "code 3 for the overdose".

NBC Bay Area reported on Victoria's death, citing police sources with "direct knowledge of the investigation" and added that she was "found in a hallway of the hotel early Thursday morning".

Authorities do not suspect foul play in relation to her death, and an official cause of Victoria's death has not yet been determined.

On January 2, Victoria's family released a statement following her passing.

They told Us Weekly: "We appreciate all of the kind words, thoughts, and prayers. Please respect our privacy during this difficult time. Thank you."

Victoria - whom Tommy had, as well as actor Austin Jones, 43, with his ex-wife, Kimberlea Cloughley - appeared in some of her dad's movies, including 2002's Men in Black II, and 2005's The Three Burials of Melquiades Estrada, which he directed.

In 2006, Tommy revealed he fired her from Melquiades Estrada but later rehired her.

He told The New Yorker: "She's a good actress, has her SAG card, speaks impeccable Spanish. When she was a baby, I told her nurse to speak to her in Spanish, but I fired my daughter [from the movie].

"She had to get up at 5 a.m. for her part. One morning, she wouldn't get out of bed. I said, 'Honey, this is work.' But she wouldn't budge, so I fired her. Then, without telling me, the production staff went over and woke her and rushed her out to the set just in time."
