Police have released little information about Mullis, but records show that he lived in the Baltimore suburb of Abingdon, Md., for about five years as a teenager.
In Abingdon, Md., a former neighbor said Mullis' questionable behavior prompted his family to move.
"My wife had just given birth to our son and I sat down and said I don't want our kid growing up next door to this guy," said Ben Wind, 38, who was a Baltimore police officer at the time.
Made threat
Among other claims, Mullis told the officer that he'd spent time in a juvenile detention center and even threatened to poison Wind's dog.
"He has been a problem child and did nothing but bad stuff," said former neighbor Jim Burns, 38, a line technician. "This kid was just blank the whole time. It's like he was empty."
Former neighbor Craig Monath, 31, a salesman, added, "He was a strange kid."
Mullis is wanted in Maryland for failure to appear on two traffic violations, records show
