Police release sketch, surveillance photos of suspect that killed cardiologist

Houston police have released a sketch and surveillance photos they hope will lead to the arrest of a man they say killed a prominent Houston doctor.

Dr. Mark Hausknecht was a cardiologist for Houston Methodist and was riding his bicycle to work on Friday when police say another man, who was also riding a bicycle, shot the doctor at least twice.

On Monday, police released a surveillance photo and video from a Metro Lift bus showing the doctor and the suspect.


On Saturday, police released a sketch of the suspect. The man is described as a white or Hispanic male, about 30 years old, around 5'10" with a slender build.

On Sunday, police released surveillance photos detailing the moments before and after the shooting.


Hausknecht worked as a cardiologist at Houston Methodist Hospital for many years as part of the DeBakey Heart and Vascular Center.

His wife Georgia Hsieh issues a statement saying, "After spending his adult life saving and prolonging the lives of others, my talented husband, Dr. Mark Hausknecht, had his life prematurely ended.”

She also added:

"So many have asked what can be done to help. While law enforcement has given you their focus on finding the criminal, I am asking you to use your vote and your voice to stem the tide of this growing public health epidemic. Write, email or tweet your Congressional Representative urging sensible gun laws. We owe it to future generations to leave a safer environment.”

Hausknecht was well known in the medical community and even helped treat President George H.W. Bush, who sent us a statement saying, "Mark was a fantastic cardiologist and a good man. I will always be grateful for his exceptional compassionate care. His family is in our prayers."

Police are asking anyone that lives near the medical center to check their surveillance cameras. Anyone with information can call HPD or they can call Crime Stoppers at 713-222-TIPS.
