COLUMBIA, Md. (WJZ) — Howard County police said a suspect is in custody in North Carolina for the murder of a woman in Columbia.
Ryan Patrick Matthias, 43, is accused of killing his ex-girlfriend, Deborah Castellano, 47.
Castellano was found shot to death in her car in the 9600 block of Basket Ring Road earlier this month.
Police learned Castellano had moved from New York after she and Matthias were arrested for a domestic violence incident. Detectives said Castellano had ended the relationship, but Matthias continued to harass and stalk her.
Police said Matthias rented a car in North Carolina the day before the murder. The vehicle was returned with more than 1,000 miles logged on it.
Matthias is being held on detainer until he is extradited to Maryland to face charges.
