Earlier story: Deandrew Hamlin is a potential suspect in the homicide investigation of the late Professor Sue Marcum being conducted by Montgomery County investigators.

Items of “evidentiary value” were found in a search of Hamlin’s residence on the 1300 block of 5th St., NW, in the District, according to Montgomery County Police spokesperson Angela Cruz.

Cruz did not elaborate on the nature of the evidence as they are part of the ongoing investigation, she said.

Hamlin, the 18-year-old arrested late Monday night when he was found driving Marcum’s stolen Jeep, is being arraigned in the D.C. Superior Court today for unauthorized use of a motor vehicle and felony fleeing, according to Cruz.

He was arrested when a license plate recognition sensor detected the stolen car on the 2800 block of Benning Road, NE, just before 11:30 p.m. Monday night. MPD officers found and pursued the car for a short distance until Hamlin crashed into a signpost at the corner of New York Avenue and M Street, NW.
