Peterson became a star after playing Dempsey’s romantic counterpart Cindy Mancini in the hit ‘80s makeover movie, but left the industry just a few years later. She had been living in Colorado for several years.
Peterson’s mother told ET that a basic toxicology test had been conducted on her daughter, but that the family was waiting on further reports to see if Peterson had any other medical conditions that may have contributed to or caused her death. She added that "this was not, in any way, a drug thing."
The rest of Peterson's family will be traveling to Colorado on Tuesday.
