A witness at Victoria Jones‘ death scene told first responders she’d been using cocaine in the lead-up to her passing … TMZ has learned.

Law enforcement sources tell TMZ … when authorities arrived at the Fairmont San Francisco hotel Thursday morning, they saw blue tinge on Victoria’s lips and fingertails and immediately suspected she’d overdosed on drugs.

We’re told a female witnesses told first responders Victoria had been doing cocaine that night.

We broke the story … Victoria had multiple run-ins with the law prior to her death, including an arrest for drug posession where cops say she told officers she’d been using cocaine.

She was also arrested months later after an alleged domestic dispute turned violent … with a man accusing her of slapping him after they argued about her drug use.

As you know … San Francisco Fire Department officials were called to the Fairmont around 3 AM Thursday for a reported medical emergency. Jones was pronounced dead at the scene.

The family released a statement just a few hours ago in which they thanked the public for their well wishes and asked for privacy.

Victoria was just 34 years old.

Victoria Jones‘ father Tommy Lee Jones and the rest of her family have released a statement in the aftermath of her passing.

The statement reads, “We appreciate all of the kind words, thoughts, and prayers. Please respect our privacy during this difficult time. Thank you.”

As you know … San Francisco Fire Department officers were called to the Fairmont San Francisco early Thursday morning for a reported medical emergency.

When they arrived, they found Victoria and pronounced her dead. The scene was then turned over to San Franscico Police and the Medical Examiner’s Officer for further investigation.

We’ve learned Victoria had multiple run-ins with the law over the years … including an arrest for drug possession — which is especially noteworthy given dispatch audio indicates she may have overdosed.

Victoria was Tommy Lee’s only daughter … he also has a son named Austin Jones. Both of them are from his marriage to Kimberlea Cloughley.

She was 34.

Lenny Dykstra — a longtime major leaguer best remembered as a member of the 1986 New York Mets — may be facing drug charges.

According to a police report obtained by TMZ, Pennsylvania State Police pulled over Dykstra on New Year’s Day after they say they saw him commit a motor vehicle code violation.

During the traffic stop, officers claim they found Dykstra had “narcotics and narcotic related equipment/paraphernalia.” Officers list Dykstra as the “arrestee” on the documents, however his high-powered attorney Matthew Blit says that’s not the case.

Lenny played in the big leagues from 1985 to 1996 with the Mets and the Philadelphia Phillies. He was a three-time All Star, a Silver Slugger winner and a member of the 1986 World Series champion Mets.
