Lonnie Franklin Jr., known by the nickname the "Grim Sleeper," was sentenced to death today in connection with the killings of women in the Los Angeles area from 1985 to 2007.
His trial began in February of this year, more than three decades after the death of the first victim.
The victims, all between the ages of 15 and 35, were strangled or shot and left in alleyways near Franklin's home in South L.A., The Associated Press said.
The Grim Sleeper moniker was given to the serial killer because of an apparent 14-year gap in the murders, from 1988 to 2002.
Franklin, a former city sanitation worker, was arrested in July 2010 after his DNA was connected to some crime scenes.
When his trial began in February of this year, he pleaded not guilty to 10 counts of murder and one count of attempted murder.
He was found guilty on all counts in May.
The jury that found him guilty recommended in June that he be sentenced to death.
