A manhunt is underway for a 45-year-old man after his long-time girlfriend, 43, and her 11-year-old daughter were found dead at their home in Columbia, Missouri. 

The Boone County Sheriff's Office in Missouri charged JT McLean with two counts of first-degree murder over the deaths of Allison Abitz, an elementary school teacher, and her daughter Jozee after finding their bodies on Sunday. 

He has a $1million cash-only bond, according to the Columbia Daily Tribune.  

McLean - who goes by many names, including John or Steven McLean or Steven Nagy - is currently on the run from police. It is not known how long he's been evading police, but the police have not had contact with him after finding the bodies, a representative from the Boone County Sheriff's Office said. 

He has connections in Missouri, Chicago, and Las Vegas, according to KY3. 

Police have not released how the mother and daughter were killed and McLean's alleged motive is unknown.
