The Los Angeles coroner says a friend of Russell Armstrong, the estranged husband of Beverly Hills "Housewife" Taylor Armstrong, also killed himself.

Alan Schram, a hedge fund manager, was found dead earlier this month of a self-inflicted gunshot wound outside his car parked on Mulholland Drive just one day after Armstrong apparently hanged himself in his Beverly Hills home.

The Los Angeles County Coroner ruled Schram's death Aug. 16 to be a suicide, said Saturday.

Schram and Armstrong were friends and members of a group called Tiger 21, which TMZ said is made up of wealthy investors who get together to discuss the markets. The Web site said Schram's money situation was not clear and he did not leave a note.
