PHOENIX (AP) — Authorities say a man accused to a sexual assault in east Phoenix also is being linked by DNA to two armed robberies in Virginia.

Phoenix police said Tuesday that 24-year-old McKinley Brown is being held on suspicion of kidnapping, sexual assault and aggravated assault.

They say forensic evidence linked Brown to a Sept. 13 sexual assault case and connected him with two armed robbery cases in Roanoke, Virginia.

Police didn’t immediately have dates or details of the Virginia cases.

It was unclear Tuesday if Brown has a lawyer yet.
