ST. PAUL, Minn. (AP) _ Authorities say a 4-year-old Minnesota boy died after his father left him in a hot SUV for hours while he worked.

The father, 26-year-old Kristopher Taylor of Apple Valley, is charged with second-degree manslaughter.

The boy died Saturday in St. Paul. Authorities say Taylor left the child in the vehicle for hours while he worked the Grillfest event at CHS Field. Taylor returned to the SUV at about 5:15 p.m. to find the boy was stiff.

The temperature reached 70 degrees Fahrenheit, and the criminal complaint says the boy was in the sun.

According to the complaint, Taylor told police he left the window open a crack and gave the boy a hand-held video game.

It isn't clear whether Taylor has an attorney to comment on his behalf.
