The former policeman charged with committing a series of murders and rapes attributed to the "Golden State Killer" has made his first court appearance in Sacramento, California.
Joseph James DeAngelo, 72, appeared in an orange prison jumpsuit, handcuffed to a wheelchair.
He was formally arraigned on two murder charges dating back to 1978.
Mr DeAngelo is a suspect in 11 other murders and 51 rapes committed across California between 1976 and 1986.
He was arrested on Tuesday at his home in Citrus Heights, a Sacramento suburb, after a 40-year manhunt.
Investigators linked him to DNA left at crime scenes, in part thanks to a genealogy database designed to trace family histories.
