George Rogowski tells Eyewitness News that he found the 2 year old son of Raina Voll, murdered along with her 7 year old son, at the corner of Union Road and Losson.
"He was really screaming, like, when the cops came, I was crying. I said, how can anybody do something like that? Leave a little kid...just drop him off and go.", said Rogowski.
Police say Shane Stevenson, 31, killed 30 year-old Raina Voll and her son, Leo Klinger, inside their apartment at the Kingswood Apartment Complex on French Road Thursday night.
The investigation began when police found the Voll's two year-old child in a stroller at the corner of Union and Losson.
That child was unharmed and is now with his biological father. Police say Stevenson is also not the biological father of the victim's seven year-old son.
The suspect had a relationship with the children's mother, but police have not elaborated on a possible motive.
Shane Stevenson, 31, pleaded not guilty in Cheektowaga Town Court Friday morning to two counts of second-degree murder.
Stevenson is being held at the Erie County Holding Center without bail.
