HOUSTON, Texas (KTRK) -- Houston police are circulating new photos showing a bicycle rider with a fully loaded backpack who they believe shot and killed a prominent cardiologist.

Throughout Monday, authorities began showing surveillance images of Dr. Mark Hausknecht and the suspect in his murder. Hausknecht, who was also on a bicycle at the time, was shot on his way to work last Friday morning.

The doctor can be seen heading north at 6700 Main and crossing into the West Holcombe Boulevard intersection.

So far, no arrests have been made, and police are searching for leads into Hausknecht's death.
