LAWRENCE, Kansas July 5, 2008 (AP) - Police say a man suspected of killing a University of Kansas law student killed himself while in custody in New Jersey.

Lawrence police say 46-year-old Adolfo Garcia-Nunez was arrested in Elizabeth, N.J., on Friday night, after police found his unoccupied pickup in that same town. Authorities say that while he was in custody in New Jersey, Garcia-Nunez took his own life.

The Lawrence Police Department said no additional information about his death or arrest would be available until its investigators return from New Jersey.

Garcia-Nunez was suspected of killing 25-year-old Jana Mackey, of Hays.

She was found dead Thursday at his Lawrence home, and a second-degree murder warrant had been issued for his arrest.
