If you live in Frisco and enjoy an early morning jog you need to keep an eye out for an aggressive coyote. Four incidents have been reported this month between 6 and 8:30 a.m. along Eldorado Parkway between Granbury Drive and Rogers Road. The most recent happened at 6 a.m. Wednesday when a jogger was running on the sidewalk of Eldorado when the animal attacked. The jogger, who is in stable condition, had "significant" injuries to the neck and underwent surgery.
