Wife-slay horror

A Queens man fatally stabbed his wife and stuffed her in a plastic bag under a bed in the family home, after hearing she had cheated on him with her stepbrother, authorities and relatives said yesterday.

Ganesh Seelall, 39, faces murder, weapon-possession, weapon-tampering and other charges.

The body of Samantha Seelall, 29, was found Thursday in the Richmond Hill home they shared with their daughters, Alecia 14, and Sara, 10.

“She told my brother she was having a relationship . . . and there was nothing [he] could do about it,’’ said Ganesh’s brother, who declined to give his name.

He identified the other man as Samantha’s “stepbrother,” Amit Bolo, who grew up with her in Guyana, and said Alecia and another relative had found the body.

An order of protection obtained in December against Seelall was still in effect, records show.
