The onetime doctor of former President George H.W. Bush was likely "targeted" when he was shot to death by a mystery gunman in Houston, police said on Thursday.

Cardiologist Mark Hausknecht, 65, was killed on Friday in a residential neighborhood as he rode his bicycle.

Houston police released a composite sketch of the suspect in the fatal shooting of prominent Dr. Mark Hausknecht on Friday, July 20, 2018.

"There is a high probability the doctor was targeted," Houston Police Chief Art Acevedo said in a statement posted Thursday on the department's Twitter account. "No other information is available, as additional details are part of the ongoing investigation."

The latest twist in the shocking case came just days after police released images from the moment right before Hausknecht was gunned down as he rode his bicycle in Houston.

The still images showed Hausknecht riding his bicycle as he crossed the busy intersection of Main Street and West Holcombe Boulevard in Southgate. The photos also showed the gunman behind the doctor just before the shooting.
