An advance copy of a book written by Scott Kimball’s cousin, Ed Coet, includes an excerpt of a jailhouse interview that appears to directly tie Kimball to the brutal 2004 murder of a woman whose dismembered body was dumped in Westminster.

In “SLK: Serial Killer,” Kimball is quoted telling a fellow inmate that he “picked up a hooker” off Colfax Avenue, gave her drugs, strangled her and “used chemicals on her to test what the acid did to her skin.”

Catrina Renee Powell, who was last seen alive on East Colfax Avenue in Denver on Oct. 24, 2004, was found dead the next day behind a strip mall at 7530 Sheridan Blvd. in Westminster.

Her hands had been cut off, and she had severe head injuries.

An autopsy report from the Adams County Coroner’s Office, which became public in September 2010, revealed that Powell had chemical burns on her body and that her cause of death included strangulation. Prior to the autopsy report becoming public, investigators working on the case hadn’t disclosed the existence of chemical burns and hadn’t revealed the exact cause of her death.

Kimball’s account comes from a May 2009 interview that FBI Special Agent Jonathan Grusing conducted with an inmate who was housed with Kimball in Park County, according to the book.

Powell’s sister-in-law, Dachelle Powell, confirms to the Camera that investigators have told her Kimball is being investigated for the murder.

The FBI refuses to comment.
