The grandson of an elderly couple found slain in their home Tuesday has been arrested in connection with their deaths.

Kyle A. Drattlo, 20, is the grandson of Erskin and Mary Louise Flugham, who were found dead in their midtown home, said a family member.

Drattlo was arrested along with two other suspects after they were stopped by police in Tonopah, Nev., Wednesday, Sgt. Maria Hawke, spokeswoman for the Tucson Police Department, said in a news release.

The suspects were driving the couple’s car when they were stopped. Tonopah is about 200 miles northwest of Las Vegas.

Also arrested were Christopher E. Terry, 23, and Brianna Harding, 21.

All three are facing two counts each of first degree murder and conspiracy to commit first degree murder; and one count of burglary, armed robbery and aggravated robbery. They were booked into the Nye County jail, where they will await extradition to Pima County.

Erskin Fulgham, 87, and Mary Louise Fulgham, 84, were found late Tuesday afternoon in their home with what police described as “obvious signs of trauma,” Hawke said.

A family member had gone by the house in the 4600 block of East North Street near the intersection of East Grant and North Swan roads, found the couple and called police.
