Alexandria police questioned an Arlington County sheriff’s deputy involved in the shooting death of a 22-year-old man in Alexandria overnight.

Authorities said that Craig Patterson, a 17-year veteran of the Arlington County sheriff’s office and an Alexandria resident, was involved in the shooting of Julian Dawkins in the 100 block of Lynhaven Drive about 12:45 a.m. Wednesday.

Dawkins, an Alexandria resident, was transported to a local hospital, where he was pronounced dead.
