Howard's attorney says his client, a former ward of the state, suffers from mental illness.
"At this point, I think that the paramount issue is to get to the bottom of his mental issues, to discover what they are and to not only identify the source of the problem but to try to rectify those," said James Mullinex, Howard's attorney.
While his attorney tries to use that defense to give some sort of response or answer as to why his client allegedly committed these crimes, court records are also showing Howard was violent toward a previous girlfriend. She says Howard attacked her and made threatening phone calls. There are now two expired orders protection against him, one in 2006 and one in 2007.
