Tyler Naughton is being charged Tuesday with second-degree murder and grand theft in connection with the death of his grandmother, Sherryl M. Kenney, the Payette County Sheriff's Office said in a release.

Kenney, 60, was found dead Sunday morning inside a residence on Northwest 2nd Avenue, south of Fruitland. Autopsy results are pending, but investigators say she died from a gunshot wound. No information has been released about a motive.

Sheriff's deputies and Fruitland Police discovered Kenney’s body just before 7 a.m. Sunday at the home. They alerted the public that Naughton was a "person of interest" and wanted in questioning in connection with Kenney's death. They assured the public that she was not killed in a home invasion robbery.

Idaho State Police arrested Naughton late Sunday in Adams County for driving Kenney’s 2006 Ford F-350 pickup, which was reported to be stolen. He was being held in the Adams County Jail on a felony grand theft charge.

At 12:45 p.m. Tuesday, Magistrate Judge Brian Lee signed two warrants for Naughton's arrest — for murder and grand theft. Naughton will be transferred to the Payette County Detention Center, where the warrants will be served. He will be arraigned at 1:30 p.m. Wednesday.

Payette County Sheriff Chad Huff said Tuesday his deputies had never been sent to the 2nd Avenue home for any types of calls prior to Sunday morning. Naughton has no criminal record other than tickets for underage drinking and smoking, according to Idaho court records.
