More images of Med Center shooter released

Man suspected of killing cardiologist shown cycling 3 minutes after allegedly firing shots

Houston police on Monday released new photo and video surveillance that show the man wanted in the slaying of Dr. Mark Hausknecht biking through an area neighborhood right after the physician’s death.

The video, taken at 8:50 a.m., shows the suspect cycling along the side of a street, wearing a blue short-sleeved polo shirt, khaki ball cap and khaki shorts. He was carrying what police have called a large, “fully loaded” olive-green backpack.

The images are the latest in a series of surveillance photos and videos that police have released since the July 20 killing.

Hausknecht, a renowned cardiologist at Houston Methodist who once treated former President George H.W. Bush, was shot in broad daylight while riding his bike to work in the Texas Medical Center. Earlier images showed Hausknecht and the suspect crossing paths on bikes around 8:47 a.m.

The 65-year-old doctor was near the intersection of Main and Holcombe when the gunman passed him from behind, police said. Two blocks later, the shooter turned around on his light-colored mountain bike and fired at least twice. The doctor, biking in his scrubs, went down immediately, and the shooter rode off northbound.

Police Chief Art Acevedo said Friday that it is “highly probable” that the shooting was targeted. A motive is still unknown.

Anyone with information is asked to call the Houston Police Department Homicide Division at 713-308-3600 or Crime Stoppers at 713-222-8477.
