A 15-hour standoff with a man suspected of shooting his neighbor ended Saturday when authorities coaxed him out of his house and made a grisly discovery: a body believed to be his mother stashed in his freezer.

Philip Schuth (search), 52, was being questioned while authorities continued to inspect his home. No charges had been filed as of Saturday afternoon.

Authorities said Schuth told them about the body during the overnight standoff, which began when he allegedly opened fire on a neighbor.

An autopsy was being performed to determine a cause of death, police said.

Schuth shot his neighbor after the man confronted Schuth about striking his 8-year-old son in the head and stealing his bicycle. The child's father was treated at a hospital and released. His wife and child were not wounded.
