The body of Drew Barrymore's half-sister Jessica was discovered in a parked car near San Diego, Tuesday. The woman who found her body, Marta Lopez, told the ABC affiliate in San Diego that she discovered Barrymore with an energy drink between her legs and white pills strewn across the passenger seat.

Lopez told 10News that she discovered Barrymore's car parked at the end of her driveway early Tuesday.

"Her car was parked right here last night around midnight," Oscar Sandoval, a neighbor who saw Barrymore's car, told 10News. "I thought she was sleeping or waiting for someone."

According to the Los Angeles Times, Barrymore worked at a Petco and would have been turned 48 this Thursday. She and Drew are daughters of the late actor John Barrymore.

"Although I only met her briefly, I wish her and her loved ones as much peace as possible, and I'm so incredibly sorry for their loss," Drew Barrymore told People.
