Police seek pickup in Louisiana serial killings

A billboard seeking information in Pam Kinamore's death was put up this week in Baton Rouge, Louisiana, offering a $75,000 reward.

BATON ROUGE, Louisiana (CNN) -- Investigators hunting for a serial killer in the slayings of three women in Baton Rouge, Louisiana, are searching for a white pickup identified by a witness in the most recent case.

Police said they haven't been able to identify the killer. DNA test results made public this week helped investigators determine that one person was responsible for all three deaths, police said.

In the most recent case, Pam Kinamore, 44, was abducted July 12 from her home. Her throat was slit, and her body was dumped under a bridge outside Baton Rouge.

On the day she was abducted, a witness told police he saw a white man of medium build driving a white 1996- or 1997-model Chevrolet pickup truck leaving Interstate 10 at the Whiskey Bay Bridge exit with what appeared to be a woman slumped in the passenger seat.

Four days later near the area where the truck was spotted, Kinamore's body was found under the bridge.

The witness is under police protection, police Cpl. Don Kelly said.

Kelly said the level of fear is high in Baton Rouge, and police have cautioned residents not to open their doors to strangers. The killer has so alarmed residents here that the governor Thursday reminded women they could apply for a weapon permit to get a gun to protect themselves. (Full story)

The first slaying occurred September 24 when Gina Wilson Green, 41, was found strangled in her apartment near the LSU campus. She died between midnight and 9 a.m. The divorcee lived alone.

Charlotte "Murray" Pace, 22, was stabbed to death midday May 31 in her townhouse, also near the university campus. Her roommate discovered the body. Police said they believe a loud, fierce struggle happened before she died.

Police haven't described the DNA evidence picked up at each crime scene. They have said no evidence suggests that the three women knew each other or that the killer was targeting women near the campus.

Police said there was no forced entry in any of the cases and that the suspect apparently either entered through an unlocked door or gained the trust of the woman who opened the door.

Kelly said police are reviewing 35 unsolved slayings of women in Baton Rouge and doing more DNA testing.

Kinamore's family has posted two billboards in the city, offering a $75,000 reward for information leading to a suspect's arrest. Kinamore was married and had a child.
