Live stream: Police say suspect in Houston doctor's murder found dead

Police say the man suspected of killing a Houston cardiologist has been found dead.

Dr. Mark Hausknecht was gunned down July 20 while riding his bike to work at Texas Medical Center. 

A manhunt has been on for suspect Joseph James Pappas. 

Authorities say Pappas had held a grudge against Hausknecht for 20 years, ever since his mother died during surgery as one of the doctor's patients. 

Hausknecht also previously operated on former President George H.W. Bush.
