Court records show Los Angeles police have seized guns, handcuffs and hundreds of other items from the home and vehicles of the man charged in the "Grim Sleeper" killings.
The items also include ammunition and car seats possibly stained with bodily fluids.
The Los Angeles Times reported Thursday that detectives have booked more than 650 items belonging to Lonnie Franklin Jr. into evidence.
Police have said none of the items tie Franklin to the killings, but DNA and ballistic tests are continuing.
Police say bullet trajectory tests and information from a woman who survived an attack have led detectives to believe Franklin shot and then sexually assaulted several victims in the front seat of his car.
Franklin has been charged with killing 10 women over a 22-year period. His attorney, Regina Laughney, has said she expects Franklin to enter a not guilty plea at his Aug. 9 arraignment.
