Victoria Louise Gatti on Tuesday morning pleaded guilty to three counts of rendering criminal assistance in the Dec. 29 murder of Jeremy McLean, 26, of Longview.

Gatti admitted to helping William Vance Reagan Jr. flee Cowlitz County after he fatally shot McLean, whose body was found at Willow Grove County Park along the Columbia River. Reagan pleaded guilty in March to first-degree aggravated murder and is serving a life sentence without the possibility of parole.

Gatti, a Longview resident, also pleaded guilty to one count of delivery of heroin and one count of selling heroin for profit. She will be sentenced Tuesday in Cowlitz County Superior Court, where he pleaded Tuesday morning.

Gatti, who was Reagan’s girlfriend, checked herself and Reagan into a Tacoma motel under her name shortly after the McLean shooting, according to investigators. Court papers said she also helped Reagan stash the motor home on Willow Grove Road.

Police said McLean, operating as an undercover informant with the Cowlitz-Wahkiakum Narcotics Task Force, bought heroin from Reagan and Gatti in the summer of 2008. Reagan admitted he shot McLean to keep him from testifying against them.
