Craine told the detective that his brother argued with Collins and started choking her while he (Louis) sodomized her. Then they switched positions, with Louis choking her and Roger sodomizing her, the detective further testified.
Police said Collins was later found dead in the house, with cocaine in her body.
Perry allegedly died the same way. Police said she was taken to a vacant house and a fight ensued. Craine told police that his brother started to choke her, and he (Louis) began sodomizing her. Then they switched again.
The district attorney's office said late Friday that despite the detective's testimony, prosecutors have not charged Roger Craine with murder.
They have, however, charged him with assault in connection with a known prostitute identified as Cheryl Williams. Louis Craine also has been charged with oral copulation and forced sodomy in an attack on Williams, police said.
The final count against Louis Craine involves an attack on a family friend, Yolanda Parker, who was visiting Craine's sister at the family home. Police said that Sandra Craine discovered her brother in the back of the house twisting Parker's arm behind her back and pushing her face into the ground.
Craine once lived in the 1000 block of West 42nd Place, according to Department of Motor Vehicle records. According to the apartment manager, Albert Nelson, Craine lived in a 20-unit apartment building with a friend, Jesse Smith, until 1986, when Smith died of a heart attack,
Nelson said Craine never had a job in the three years that he lived with Smith, although police listed his former occupation as construction worker. The apartment manager recalled that Craine spent much of his time sipping beer on the front stoop of the building. Craine's only apparent means of support, Nelson said, were welfare checks.
"He was always calm," Nelson said. "He never gave me any problems. He'd just sit on the step and never bothered nobody."
Nelson said the body of a black woman who had been murdered was discovered behind the apartment building two years ago. Craine was no longer living in the building when that body was discovered.
However, other residents of the building and other neighbors said they were questioned as recently as Wednesday about Craine's possible connection to the crime. Residents could not recall the victim's name and other details of the crime.
Despite Craine's arrest, a long-time critic of the police investigation said Friday that the addition of an 18th victim indicates that there may be more Southside Slayer victims who police have not counted.
"First, we're glad that anybody who murders anybody is arrested," said Margaret Prescod, leader of the Black Coalition Fighting Back Serial Murders. "So, if it is a break in the case, we are very pleased. What concerns us is we have been worried all along the numbers (of victims) were greater than 17. . . ."
Craine is scheduled to be arraigned Tuesday in Compton Municipal Court in the two Southside Slayer deaths. He is currently being held without bail in County Jail in connection with the three other murders.
