Police believe a "downturn" in a man's relationship with his girlfriend led to a standoff in Heidelberg Township Sunday night.
Officers rushed to the home of Lance E. Moore, 42, of 6751 York Road (Route 116) about 7 p.m. after Moore's mother called 911 and said Moore was trying to kill her, according to Southwestern Regional Police.
The mother, whose name wasn't released, ran to the first arriving patrol car and told the officer her son had a gun and she feared for her life, police said. The officer put her in his cruiser and they quickly left the area.
Other officers spotted Moore in his backyard holding a gun and running inside his home, police said.
Officers surrounded the home and called in the county's Quick Response Team, a SWAT-type unit.
About 11:30 p.m., QRT members began trying different techniques to make contact with Moore, but he would not communicate with them, police said.
Four hours later, about 3:30 a.m. Monday, QRT members found Moore hiding in the basement of his home, police said. He was arrested without further incident.
Moore was taken to York Hospital for an evaluation, then taken to the county's central booking unit to be arraigned on charges of simple assault, making terroristic threats and reckless endangerment, police said.
Officers found a "variety" of guns inside Moore's home, according to police. No shots were fired during the incident.
The standoff closed Route 116 for 8-1/2 hours. Fire police detoured traffic around the area.
Assisting Southwestern Regional Police and QRT at the scene were officers from West Manheim Township Police and Penn Township Police.
