On Monday, Pittsburgh police arrested Melvin Banks in connection to three stabbings in the Lincoln-Lemington area.

One of those victims was Greg Walker, who died Saturday. Walker was mentally disabled and recently started living with his sister, his mother told KDKA on Monday.

On Wednesday, Walker’s friends and family placed flowers, candles and signs near the Dorothy Day Apartments.

“We’re going to miss him so much. He was a good kid, good man. His mother is hurting the most. She is just lost without him,” said Daniel McKee, Walker’s stepfather.
