NORTH LAS VEGAS, Nev. — A southern Nevada gun dealer wants to auction a handgun once owned by a rogue former LAPD officer who killed four people and fatally shot himself during a manhunt in February.

George Bramlett, owner of Bargain Pawn, said he plans to donate the money to the families of two California police officers Dorner killed. But administrators handling the funds for San Bernardino County Sheriff Deputy Jeremiah MacKay and Riverside police Officer Michael Crain say the families don't want the money.

Bramlett posted the gun for auction Tuesday on a website, gunbroker.com, along with images of the sales receipt listing Dorner's date of birth, California driver's license number and La Palma, Calif., address. Bramlett bought the .38 special revolver from Dorner in January for $50.

By today,it, Jeremy and Mike were murdered by this animal. We wouldn't want to do that to the family members."

The San Bernardino Sheriff's Employee Assistance Team "would not knowingly accept a donation to the MacKay family which was in any way associated with the suspect," Cindy Bachman, a sheriff's office spokeswoman, said in an email.

Dorner, 33, had a home in Las Vegas where he kept several guns around the house, according to a manicurist who rented a room from him in the summer of 2008.

"On the floor, under the cushions. When I would clean, I would find guns," J'Anna Viskoc said in a February interview with The Associated Press.

Bramlett, a licensed federal firearms dealer who has been in business since 1986, said Dorner was an occasional customer.
