After news broke of the Wednesday death of Sons of Anarchy star Johnny Lewis -- who was also named a murder suspect in the death of his landlady, Catherine Davis -- more details are emerging about the life of the actor, who was 28.

Back in 2004, Lewis (who also appeared on The OC, Alien Vs. Predator and American Dream) promoted Narcanon, an anti-drug program created by the Church of Scientology, the Daily News reports. The paper also writes that Lewis' parents were both active Scientologists, with his father, Michael Lewis, appearing in an instructional self-help video based on the works of L. Ron Hubbard, the Church's founder.

Although toxicology reports are pending, authorities are investigating whether Lewis was on a new, synthetic drug known as "Smiles" before the violent rampage at 81-year-old Davis' house in the Los Feliz area of Los Angeles.

On Wednesday, Lewis got into a violent altercation with Davis, neighbor Daniel Blackburn and a handyman; police report that Davis was bludgeoned to death, and Lewis eventually jumped or fell off the roof, leading to his death.

"We still don't have a motive, whether this was just the random act of somebody acting crazy or whether there was some type of altercation or dispute," LAPD Commander Andrew Smith told the Daily News.

"There are several new drugs that are coming out after bath salts got outlawed," Smith said of the "Smiles" report. "We don't have any hard evidence that he was on anything."

Lewis, who dated Katy Perry back in 2005 and 2006, was arrested numerous times in 2012 for assault, breaking and entering and burglary -- spending time in court-ordered rehab as well as jail.

A recent report written by a probation officer gave a troubling warning sign about the star's state of mind.

"This officer is very concerned for the well being of not only the community but that of the defendant. It is apparent to this officer that the defendant suffers from some form of chemical dependency, mental health issue and a lack of permanent housing," writes the report, according to the Daily News.

His ex Katy Perry, a source told Us Weekly, is "devastated" by his death.  "It's really sad. She could never help him and couldn't [let herself] go in that direction."
