Shane Walker was charged with murder, manslaughter, arson and criminal possession of a weapon. Police say the suspect is believed to be the children’s father and lived with them in the home. He was taken into custody after he was found walking along the Brooklyn Queens Expressway earlier Saturday.

Authorities were called to a house along Palisade Street, near Lily Pond Avenue in Arrochar shortly before around 10:30 a.m. due to an assault in progress, police said.

When they arrived, authorities found the residence filled with smoke. A small fire was extinguished by authorities, police said.

Officers found the bodies of Ivan Walker, 2; Elia Walker, 3 and Alla Ausheva, 37, in the home.  A source told PIX11’s Nicole Johnson they were found on the bed, face down. They were pronounced dead at the scene.

Police say the man and woman were both in the military.
