A 75-year-old Orem man died after his fishing boat capsized Tuesday night in Strawberry Reservoir.

Joseph Overman, 75, was fishing with William W. Williams, 65, also of Orem, in a reservoir's northeast bay about 8:30 p.m. when one of the men stood up, causing their 12-foot fishing boat to capsize, said Wasatch County Sheriff Edd Thacker.The men, hanging on to flotation devices, screamed for help. Nearby fishermen came to their aid in the darkness.

Williams was pulled to safety but Overman, clinging to a cushion, was dead face-down in the water when rescuers reached him, said Thacker. It was not immediately known whether Overman drowned or died of a heart attack.
