St. Louis, Mo. – A St. Louis police officer has died, a month after suffering a seemingly minor injury in the line of duty.
James Branson, 36, died Sunday from a blood clot that formed after breaking an ankle in a car accident.
"It looks like it might have been a blood clot from the ankle injury," police spokesman Richard Wilkes said. "It's just frightening."
Branson and partner Jermaine Jackson were chasing two carjacking suspects last month when their police cruiser hit another car. Jackson is still hospitalized.
Branson was treated for the broken ankle at the time of the wreck and sent home. Over the weekend, he was visiting a friend when he complained of chest pains, and died at a Belleville hospital.
The suspected carjackers have not been caught.
