David Linthicum, a 24-year-old white man, was arrested by the Harford County Sheriff’s Office in February after violent encounters with police that left two officers with gunshot wounds — one of them was placed on life support. As officers from a special weapons and tactics unit closed in on Linthicum, who was holed up in a wooded area in Harford County, they believed he was armed with weapons from a police vehicle. Police said allegedly stolen that vehicle the night before to escape authorities.
