SEAL BEACH, Calif. (KTLA) -- The man accused in the deadly Seal Beach salon shooting rampage pleaded not guilty in court Wednesday.
Scott Dekraai appeared in chains and an orange jail jumpsuit for his brief arraignment.
Prosecutors are seeking the death penalty in the case, the Orange County district attorney's office said.
Dekraai is being held without bail.
Prosecutors say the disgruntled ex-husband murdered eight people, including his former wife, during the two-minute massacre.
Dekraai allegedly stormed Salon Meritage about 1:30 p.m. Oct. 12 with the intent of killing his ex-wife, Michelle Fournier, a stylist at the salon.
He wore a bulletproof vest, was armed with 3 guns and shot at "anyone close enough to hit," Orange County District Attorney Tony Rackauckas said.
He stopped to reload his weapon and continued on his deadly rampage, according to Rackauckas.
Dekraai executed his victims, shooting some in the head, others in the chest, Rackauckas said.
He allegedly shot his victims multiple times to make sure they were dead.
The victims were identified as: Scott Dekraai's ex-wife Michelle Fournier, 48; Randy Fannin, 62, the salon owner; Dave Caouette, 64; Victoria Buzzo, 54; Laura Webb, 46; Michelle Fast, 47; Lucia Bernice Kondas, 65; and Christy Wilson, 47. Caouette was shot as he sat in his Range Rover outside the salon.
Harriet Stretz, 73, the mother of one of the hairdressers, was also wounded.
Court documents show Dekraai filed for divorce in 2007.
Rackauckas said a custody battle over the couple's 8-year-old son motivated the suspect.
In May, Fournier claimed in court papers that Dekraai was mentally unstable and had threatened to kill himself or someone else at least once.
Fournier's relatives said Dekraai devoted seemingly unlimited resources to try to take custody away from his ex-wife.
He accused her of being an "uncaring, selfish drunk" and later of abusing their son.
She, in turn, accused him of "grilling" their son about his mother for so long that it left the child in tears.
