Earlier this year Julia Roberts' half-sister committed suicide and now the half-sister of Drew Barrymore has done the same. Police in a San Diego suburb said they found Jessica Barrymore's body slumped in her car yesterday blocking the driveway of another woman who called police. Barrymore had a SoBe energy drink and pills scattered all over her and the car. Another neighbor said he noticed the car blocking the driveway beginning about midnight. Jessica was 47 and had been very despondent over the past few days.
