The remains of a suspected homicide victim were recovered from under a slab of cement and dirt the back yard of a north Kingman home Monday night. The Mohave County sheriff’s office says the remains believed to be those of John Holland, 65, were transported to the medical examiner’s office for positive identification and cause of death determinations.
Public works and sheriff’s office personnel began cutting and breaking up concrete at the home in the 3700 block of Lass Avenue early Monday and the first body part was located shortly after 6:00 p.m. The coroner was summoned to the scene to coordinate the recovery effort which was completed at about 9:00 p.m.
A failed suicide attempt in Laughlin by Richard Polaski, 63, Kingman, prompted his confession that he stabbed and killed Holland during a June, 2015 argument, according to the Sheriff’s Office. Court records indicate Polaski told authorities he put Holland’s body in a hole in the backyard of the Lass Avenue property and covered it with three feet of concrete.
Polaski is held in the county jail in Kingman on a first degree murder charge. Prosecutor Jonathan Taylor said additional charges are contemplated pending completion of an ongoing investigation.
Court records reveal Polaski told authorities a woman helped him forge and falsify documents to gain power of attorney to assume control of Holland’s assets, including a trust account, residential property and vehicles.
Taylor said no one else has been charged at this point. Polaski’s lawyer, Robin Puchek, declines comment.
