Their bodies were dumped in alleys and garbage bins in south Los Angeles, some naked, some covered with mattresses and rubbish. Most had been shot in the chest after some type of sexual contact, others strangled.
As prosecutor Beth Silverman showed photo after photo of the 10 victims to a packed courtroom today, family members of the dead young women shook as they wept. Some covered their faces, others had to walk out.
It was an emotional beginning to the long-awaited "Grim Sleeper" trial, which comes more than 30 years after the first victim's death.

The "Grim Sleeper" nickname was coined because of an apparent 14-year gap in the murders between 1988 and 2002.
Franklin, 63, has been awaiting trial behind bars for nearly six years since his arrest in July 2010. The trial is expected to last up to four months.
In opening statements to jurors, Silverman said Franklin took advantage of the crack cocaine epidemic in south Los Angeles, targeting women "willing to sell their bodies and their souls to gratify their dependency on this powerful drug".
Autopsies showed all but one victim had cocaine in their systems when they were killed, and some had turned to prostitution.
"This was the perfect opportunity for someone who preyed on women," Silverman said.

Silverman continued: "It was the perfect place and time for a serial killer to roam the streets of Los Angeles, really without detection."
Franklin's lawyer, Seymour Amster, won't deliver his opening statements until later in the trial.
Last week, Amster told AP that "it's not over until it's over."
"There's more to it than people want to believe," Amster said. "It's up to the prosecution to prove the case beyond a reasonable doubt."
As many as 30 detectives investigated the Grim Sleeper killings in the 1980s, but they exhausted leads within a few years.

Police arrested Franklin in July 2010 after his DNA was connected to more than a dozen crime scenes. An officer posing as a busboy at a pizza parlour got DNA samples from dishes and utensils Franklin had been eating with at a birthday party.
Family members of the Grim Sleeper victims and a survivor of the attacks have been frustrated by repeated delays in the case and were eager for the opening statements.
The Grim Sleeper was among at least three serial killers who stalked Los Angeles women during a crack cocaine epidemic in the 1980s and 1990s. The attacks were dubbed the "Southside Slayer" killings before authorities concluded more than one attacker was involved.
Chester Turner has been convicted of killing 14 women, including one who was pregnant, and was sentenced to death in 2007. Michael Hughes was sentenced to death in 2012 for strangling a 15-year-old girl and two women. He previously got life for four killings.
