Authorities had been searching for Austin Robert Drummond since July 29, when four people were found dead and an infant was abandoned in northwest Tennessee.

Residents were asked to check their security cameras, resulting in several sightings of Drummond near homes, where he was seen knocking on doors with a firearm.

A manhunt for the suspect in the Tennessee kidnappings and killings of four people, including three from the same family, ended Tuesday, police said.
