Authorities in Houston have released additional surveillance video and images from their investigation into the brazen fatal shooting of the onetime doctor to former President George H.W. Bush.

Cardiologist Mark Hausknecht, 65, was killed June 20 in a residential neighborhood as he rode his bicycle in broad daylight. The shooter was also riding a bike when he rode past the doctor and "turned and fired two shots," police said during a news conference later that day.

In a post on the Houston Methodist Hospital's website, the president and CEO said Hausknecht had been heading to work when he was shot.

On June 23, police released images from the moment right before Hausknecht was gunned down as he rode his bicycle in Houston.
