Drew Barrymore's half-brother believes Jessica's death was a 'drug misadventure'

Drew Barrymore's half-brother, John Blyth Barrymore, has revealed that he doesn't think that his younger sister Jessica's death was a suicide, but was a "drug misadventure" from mixing alcohol and pills.

The 'Charlie's Angels' star's half-brother told the New York Daily News that some empty vodka bottles and a couple bags of meth were found in the vehicle along with dozens of white pills scattered across the passenger seat, Us Magazine reported.

According to John, this was a similar case like with Heath Ledger.

John further said that Jessica was a kindred spirit girl.
