Four prescription medications were found at the time of Cathriona White’s death, authorities confirm to people.
Assistant Chief Coroner Ed Winter says that there were multiple prescription pill bottles located near the body of Jim Carrey‘s girlfriend when she was pronounced dead in her Los Angeles home of an apparent suicide on Sept. 28, and none of the prescriptions were in White’s name.
“There were four prescriptions: Ambien, Percocet, Propranolol and Zofran,” Winter says, adding that they “were not [written] in her name.”
Of the four prescriptions, Winter explains that three were under one name while the fourth was under another name.
Ambien is a sleep aide drug, Percocet is a narcotic painkiller, Propranolol is a blood pressure medication that can be used to treat migraines and anxiety, and Zofran is a anti-nausea drug often given to cancer patients
According to TMZ, law enforcement sources said that the name on three of the pill bottles was an alias for Carrey.
The Los Angeles County Coroner’s Office and L.A.P.D. could not confirm that information to PEOPLE, and a rep for Carrey did not respond to a request for comment.
While the prescriptions were found near her body, it is still unclear what ultimately caused her death. According to Winter, an autopsy has been completed but the cause of death is “deferred,” pending the results of a full toxicology report.
Winter previously told PEOPLE that along with the pills, multiple notes were found at the scene, including one addressed to Carrey.
“There were several notes found,” Winter said. And while he doesn’t know the exact contents of the letters, “There was a note [addressed] to Mr. Carrey.”
Meanwhile, Carrey – who dated the 30-year-old on and off for three years after they first met in 2012 on a movie set – is “doing everything he can to help,” a source tells PEOPLE. “He is devastated, but can’t imagine how her family must feel.”
The actor has been assisting White’s family since they arrived stateside last week to help make arrangements to bring her body back to her native Ireland.
“Jim arranged for his driver to pick up Cathriona’s family from LAX. Her family has access to his car during this awful visit to L.A.,” says the source, adding that the actor is “helping out financially as well.”
He has also been spotted meeting with White’s sister, Lisa, on two separate occasions. On Wednesday, he spoke with Lisa at his L.A. home, and was photographed arriving at White’s house late Thursday night.
“Jim visited Cathriona’s house last night to help her sister Lisa,” explains the source, who says this isn’t the first time the actor has met White’s family. “Jim has spent time with Lisa in the past during her Los Angeles visits. He feels it’s his obligation to do whatever he can to help Lisa.”
