"Can't Buy Me Love" star Amanda Peterson's death shocked and saddened fans of the '80s film and the Hollywood community on Monday — but as medical examiners search for a cause of death, the actress' tragic story continues to unfold.

Peterson, 43, was reportedly arrested four times over the past two decades in her hometown of Greeley, Colorado, most recently on a May 2012 DUI and drug paraphernalia charge.

Additional arrests in 2000, 2003 and 2005 and their subsequent booking photos, unearthed by People magazine, show a significant departure from the fresh face that played opposite Patrick Dempsey's in romantic comedy — and one even displays two black eyes.

Peterson's mother, Sylvia, confirmed that her daughter battled addiction but had been clean "for a long time." In a separate interview with Entertainment Tonight, Sylvia was adamant drugs did not factor into her daughter's death.

"This was not, in any way, a drug thing," she said, also repeating earlier speculation that Peterson suffered sleep apnea and the condition possibly played a part in her death.

Peterson stopped responding to calls and texts on July 3, two days before she was discovered in her home. Sylvia told People about her daughter's mental state when the two spoke for the last time.

"She was in bed, and she'd had a wonderful day, and we were planning on a dinner the next day," she said. "So it was just a very, very big surprise."

It wasn't all struggles for Peterson. Local photographer Ryan Hartsock recruited her for a car-and-motorcycle themed photo shoot in 2012, and said outreach from fans often gave her comfort.

"She had the greatest smile. I know it brightened her day when she got all the emails and fan mail from everybody," Hartsock said. "Really any time that we were together she was a kindhearted, great person."

Peterson's additional film credits include the 1989 Kirk Cameron-Jami Gertz drama "Listen to Me," a 1990 appearance on Neil Patrick Harris' star-making sitcom "Doogie Howser, M.D." and a 1994 film called "WindRunner."
