Police have obtained a warrant charging Linda McCorkle, 48, of Chillum, with armed robbery and second-degree assault in the Jan. 12 incident, authorities said.

Julie Parker, a Prince George’s County police spokesman, said several tipsters called to identify McCorkle as the 84-year-old woman’s attacker after news outlets published or aired surveillance footage of her Wednesday.

“Our phones immediately started ringing,” Parker said. “The information that came in as a result of the intense media coverage helped lead us to this suspect.”

Last Thursday, police said, McCorkle and three young children approached the 84-year-old woman in the parking lot of Murry’s Steaks on New Hampshire Avenue in the Langley Park area. McCorkle told the 84-year-old she needed to cash a check because the children had not eaten in days, police said.

When the 84-year-old agreed to drive her to the Bank of America down the street, McCorkle handed the kids to another woman, police said. During the drive, she threatened the 84-year-old, saying if she did not withdraw and hand over several thousand dollars, she would be shot, police said.

The 84-year-old did as she was told and drove McCorkle back to Murry’s after she had completed the transaction, police have said. She was not hurt.

Parker said investigators are exploring whether McCorkle might have been involved in similar crimes, but they have found no evidence of that so far. She said they also are working to determine who the other woman and children were.

Anyone with information on McCorkle’s whereabouts or any other information about the case is asked to call the Prince George’s County Police Department’s District I investigative section at (301) 699-2601.
