MOUNT VERNON - An 85-year-old grandmother has been killed in Mount Vernon.

Police discovered the body of Emma Gruber Tuesday night at the bottom of her basement stairs after her family reported her missing.

Investigators believe she may have walked in on thieves who were stealing her water meter to re-sell the copper inside.

Neighbors are in disbelief. "It's definitely shocking. She was 85 years old. Whatever they were trying to get from her, it was unnecessary to do that," says Jermaine Hughley.

Anyone with information is urged to contact Mount Vernon police at (914) 665-2500.
