SAN DIEGO (CNS) - A former Navy man who made hundreds of calls to a woman's telephone and tracked her through GPS technology after she made clear their relationship was over will undergo a psychiatric evaluation before he is sentenced, a judge said Monday.

Michael Lutz, 30, pleaded guilty to a cyberstalking charge on June 8 and faces up to five years in prison.

On Monday, U.S. District Judge Larry Burns rescheduled sentencing to Dec. 6 so Lutz can be evaluated, said Assistant U.S. Attorney Emily Keifer.

According to court documents, Lutz once chased the victim throughout a shopping mall, followed her into a women's bathroom and climbed under a locked stall to confront her.

He made hundreds of calls to the victim, tracked her through Global Positioning Technology on her phone, and illegally downloaded a program onto her computer that allowed him to spy on her Internet use, according to prosecutors.

Lutz also allegedly created a Facebook profile in the name and image of another person so he could continue interacting with the unsuspecting victim, who had obtained a restraining order against him.

Lutz, who was stationed in San Diego at the time of the cyberstalking, has since left the military.
