Sgt. Mike Moran with the Greeley, Colo., police department told the Associated Press that Peterson's body was found alone in an apartment Sunday. Moran said an investigation is ongoing but no other information was available.

Peterson's mother, Sylvia Peterson, told CNN that the actress died Friday morning.

"It's a big loss. Such a loveable person," Peterson told CNN. "She had some medical problems with her heart but we don't know the cause yet."

Peterson first appeared on the big screen at age 9 as a dancer in the 1982 adaptation of the play Annie, directed by John Huston. She would go on to make several television appearances, including an episode of Silver Spoons with Ricky Schroder.

Peterson's next film role was as Ethan Hawke's crush in the 1985 Sci-Fi comedy Explorers.

The role that brought her the most fame was as cheerleader Cindy Mancini, playing opposite Patrick Dempsey in Can't Buy Me Love. Dempsey played a high school nerd who pays the popular cheerleader Cindy to pretend to be his girlfriend. Of course, they end up really falling for each other.

Peterson's last film was Windrunner, in 1994, according to IMDB.com.
