MINNEAPOLIS (WCCO) — The man who admitted to opening fire inside a Minnesota health clinic last month appeared before a judge Monday morning via internet.

Gregory Ulrich, 67, is facing charges of second-degree murder, attempted murder and setting off explosive devices in connection to the Feb. 9 shooting at the Buffalo clinic that left four people hurt and one woman dead. Buffalo is located just west of the Twin Cities metro area.

According to a criminal complaint, Ulrich walked into the Allina Clinic Crossroads and started shooting. Investigators say Ulrich also set off homemade bombs inside the clinic.

The attack killed 37-year-old Lindsay Overbay, a medical assistant at the clinic and a mother of two young children.

During the morning hearing, Ulrich’s attorney asked for a mental health evaluation to be performed on his client. The judge granted that request.

Ulrich faces up to 40 years in prison for the murder charge alone. His next court appearance is slated for May 20.
