A father killed his daughter’s 19-year-old boyfriend by repeatedly stabbing him and then stuffing him inside a car trunk after finding he’d sold her into a sex trafficking ring, detectives have revealed.

John Eisenman, 60, was charged with first-degree murder and is being held on a $1 million bond at Spokane County Jail in Washington.

Andrew Sorensen’s rotting corpse was found in the trunk of an abandoned car on East Everett Avenue in Spokane last month, police said on Monday. Detectives believe he was killed in November last year.

Eisenman discovered in October of that year that his juvenile daughter had been sex trafficked into Seattle by Sorensen for $1,000, according to a police press release.

He was able to rescue the girl from the city and bring her back to Spokane that month.

He then learned that Sorensen was going to be at an address in Airway Heights so he drove there and waited for the 19-year-old to arrive.

‘During that encounter Eisenman abducted the victim, tying him up and placing him in the trunk of a vehicle. Eisenman subsequently assaulted the victim by hitting him in the head with a cinder block and then stabbed him repeatedly, causing his death,’ police said.

‘After the homicide, Eisenman drove the vehicle to a remote area in North Spokane County and abandoned the car with the body still inside.’

The car was left in the countryside until last month when someone drove it to Spokane and left it on East Everett Avenue. Officials said they do not believe that person knew there was a corpse in the back.

The body was found when people began searching through the vehicle.

Amber Hellmann said her boyfriend and another friend said they noticed the car had been there for a while.

‘They were just looking around and for some reason, they decided to look in the trunk and all I hear is, ‘there’s a body,” she told KHQ-TV.

Police said Eisenman was arrested and surrendered to officers without incident. Prior to his detention he had no recent violent criminal history.
