MOSCOW, Aug. 3 (UPI) -- Police in Russia are probing why a man tossed a grenade into his sister-in-law's yard and set fire to a son's house before committing suicide, officials said.

A regional Investigative Committee spokesman said preliminary reports indicated the 61-year-old Armavir resident was extremely jealous and fought with his wife so often she left him to live with their oldest son in the Krasnodar region, RIA Novosti reported Friday.

On Thursday, the man went to his sister-in-law's to demand his wife return home.

"He demanded [from the wife's sister] that his wife return home to him, threatening violence at the same time," the preliminary report indicated. "He made a similar demand to his younger son, who lives in the neighborhood. Without waiting for any response, the man detonated a grenade in her yard."

After detonating the grenade, investigators said the man set his son's home on fire. His son was not home at the time, RIA Novosti said.

The man then returned to his home, set fire to it, locked the door and shot himself, the report said.
