A Pennsylvania man has been arrested in connection with the murder of a prominent Washington, D.C., photographer, who was reported missing from Huntingtown, Maryland, on Sunday.

Calvert County officials in Maryland on Thursday announced the arrest of Brandon R. Holbrook, 47 of Reedsville, Pennsylvania, in connection to the murder of Joseph Anthony Shymanski, a 51-year-old father of two known for his photography that he sold at a weekly outdoor market on Washington, D.C.'s Capitol Hill.

After executing "an extensive search warrant" on Monday at Shymanski's residence in Huntingtown, investigators suspected foul play and identified their suspect.

Detectives with the Criminal Investigative Bureau (CIB) then traveled to Reedsville, where they executed several search warrants and took Holbrook into custody on charges of first-degree murder, second-degree murder and first-degree assault.
