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

As the weeklong manhunt for the suspect arrested in the killings of four relatives of a baby found abandoned in Tennessee came to an end on Tuesday, police revealed the suspect’s girlfriend is related to the victims.

Austin Drummond, who was wanted in a quadruple murder in West Tennessee, was taken into custody Tuesday morning, according to law enforcement.
