GERMANTOWN - Attorney General J.B. Van Hollen and Germantown Chief of Police Peter Hoell announced that the Germantown Police Department, in conjunction with the Wisconsin Department of Justice, arrested Mark J. Libecki at 7:15 a.m. this morning for the murder of Theresa Wesolowski. The suspect was taken into custody exiting his place of employment.


"I am pleased that the work of law enforcement and their cooperative efforts resulted in the arrest of a suspect in this matter," said Attorney General J.B. Van Hollen. "My thoughts are with the family and friends of Theresa."
