Houston police say an SUV driven by trial attorney John O'Quinn was going nearly twice the speed limit during rainy conditions when it wrecked and he died. The Oct. 29 accident on Allen Parkway also killed a passenger, Johnny Cutliff, who worked for O'Quinn. Police cited crash data from the computer of the Chevrolet Suburban that indicted the vehicle was traveling up to 79 mph before the SUV went out of control and hit a tree. The speed limit is 40 miles per hour in the area.
