State police said Tuesday the man who killed five people in a southeast Indiana shooting rampage over the weekend was still at large.
Authorities launched a murder investigation and warned residents to stay attentive, keep their doors locked and report to authorities if they found anything suspicious.
The police said evidence showed that the killer was not among the five people whose bodies were found in rural Franklin County near Laurel.
Anywhere in the United States or anywhere in the world, we're going to be going after them, USA Today quoted Indiana State Police Sgt. Jerry Goodin as saying.
At a news conference on Tuesday night, Franklin County Coroner Wanda Lee revealed the identities of the victims: Angela A. Napier, 47; Roy Napier, 50; Melissa Napier, 23; Jacob L. Napier, 18; and Henry Smith, 43.
All of them were found dead on Sunday at two properties near the town of Laurel. The Napiers appeared to be from one family and Smith was identified as their neighbor.
Four victims suffered gunshot wounds on their heads.
Authorities said that they had not found any motive behind the killings. They did not identify any specific persons of interest in the case.
Goodin said police were investigating the case and continued to guard the crime scene.
He told residents: Make sure you lock your doors. ... Go on about your regular business, but don't take any chances.
