A 70-year-old Vancouver father was arrested on Memorial Day after allegedly shooting his 50-year-old son.

William Wayne Terry, 70, is being held at the Clark County Jail on suspicion of first-degree assault. Police said he is accused of shooting his son, Mark Christopher Terry.

The shooting was reported about 11:40 a.m. Monday at William Terry’s home at 8619 Mount Thielson Ave., in the Vancouver Heights neighborhood.

Police arrived to find Mark Terry outside a neighbor’s house, suffering from a gunshot wound, reportedly to the abdomen.

William Terry was inside the house. He initially refused to come out of the home, leading to a SWAT call-out and a brief standoff before he surrendered. He is expected to make a court appearance Tuesday morning.
