LAUREL, IN (FOX19) - A person of interest in the murders of five people in Franklin County is in police custody.

David E. Ison, 46, from Glenwood, Ind. was arrested Tuesday night for Attempted Armed Robbery. A warrant was issued Tuesday out of the Ripley County Circuit Court after a five month investigation related to an attempted Robbery at the Triplett's Drug Store in Osgood, Ind.

In that attempted Armed Robbery, Ison is accused of trying to rob the pharmacy and displaying a gun. He escaped the scene but left some of his DNA that was later collected by Crime Scene Technicians from the Indiana State Police Post at Versailles.

The DNA was analyzed by the Indiana State Police Laboratory and a positive identification of David E. Ison was made.

During the arrest of Ison, detectives from the Indiana State Police Post at Versailles developed information that possibly associated him to the five deceased victims on Stipps Hill Road in Franklin County. A search warrant was also conducted in conjunction with the arrest at a residence in Glenwood, Ind in Fayette County where Ison was staying.

Based on the results of the search warrant, Indiana State Police detectives have identified Ison as a person of interest in the ongoing murder investigation.

The Franklin County Sheriff stated in the news conference Wednesday afternoon that he is "confident they have a person involved in the shooting in custody."

Ison has a lengthy criminal history that includes several burglary charges, as well as armed robbery, forgery, counterfeiting, criminal confinement and theft.

Angela Napier, 47, her estranged husband Roy Napier, 50, and two of their adult children, Melissa Napier, 23, Jacob Napier, 18, and a neighbor Henry Smith, 43, were found dead around 1:30 p.m. Sunday. All members of the Napier family suffered gunshot wounds to the head, and Smith had a gunshot wound to the chest.

Their bodies were discovered after a 4-year-old girl was found wandering alone in the street. WXIN reports the girl is the daughter of Melissa Napier.

Investigators believe drugs could be involved in the deaths. Indiana State Police say this is an ongoing investigation.
