The Los Angeles serial killer known as the "Grim Sleeper" faces the death penalty when he is sentenced for the murders of nine women and a teenage girl.

Lonnie Franklin Jr. faces formal sentencing Wednesday after a jury found him guilty and said he should be executed.

Franklin was convicted of murders spanning more than two decades that went unsolved for years until police realized they were the work of one killer and made a greater effort to catch him.

Community members criticized police for not investigating because the victims were poor, black and some were prostitutes and drug users.

The killer earned his moniker for an apparent hiatus in slayings, though authorities now think he never rested.

The defense is seeking a new trial and wants to the death sentence set aside.
