A man suspected in the targeted killing of four family members and leaving their baby abandoned in front of a stranger's home has been arrested in rural Tennessee.

The weeklong manhunt for Austin Robert Drummond ended after local authorities instituted an early morning shelter-in-place for residents near Jackson after he was sighted there. Residents were warned to lock doors and windows as police searched for him.

Police accuse Drummond, 28, of killing the baby's parents, grandmother and teenaged uncle before abandoning the infant in front of stranger's house.

The arrest "marks an important step in restoring safety to our community," Jackson Police Chief Thom Corley said.

The abandoned baby, left in a car seat, was found in front of a stranger's home in Tigrett, Tennessee on July 29 prompting a search for the parents.
