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 Robert Drummond, 28, faces charges in the deaths last month of James Matthew Wilson, 21; Adriana Williams, 20; Cortney Rose, 38; and Braydon Williams, 15.

The authorities had been searching for Austin Drummond in connection with the killing of four people and the abandonment of a baby in a yard.
