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

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.

Drummond's criminal past stretches over a decade into the past, as he was convicted of aggravated robbery in 2014 after robbing a convenience store in Jackson, Tennessee the year prior, according to WREG-TV in Memphis. The suspect spent 13 years behind bars, during which he picked up an additional charge for retaliation, according to Fox News.
