Three people accused of murdering an elderly Tucson couple and stealing their car pleaded not guilty Thursday in Pima County Superior Court.

Kyle Austin Drattlo, 20, Brianna Harding, 21, and Christopher Edward Terry, 23, are charged with first-degree murder in the deaths of Drattlo’s grandparents, Erskin and Mary Fulgham, on July 23.

None of the defendants made any statement during the brief video arraignments.

In addition to two counts of first-degree murder, all three pleaded not guilty to two counts of conspiracy to commit fist-degree murder, burglary in the first degree, armed robbery, aggravated robbery and theft of a means of transportation.

Erskin Fulgham, 87, and Mary Fulgham, 84, were found dead in their home in the 4600 block of East North Street, near  North Swan and East Grant roads.

Court filings said the couple appeared to have been killed with a knife.

Drattlo, Harding and Terry were arrested in Tonopah, Nev., the day after the Fulghams’ bodies were found.

A Nye County sheriff’s deputy pulled over the suspects for speeding on U.S. Highway 95 outside Tonopah. The vehicle they were in had been reported as stolen from the Fulghams.

The deputy arrested the three, who were held in the Nye County jail and later extradited to Tucson.

After accepting their not-guilty pleas, court hearing officer Roger L. Duncan scheduled a Sept. 23 case-management conference for each defendant.
