Houston police release new surveillance video of suspect in doctor's murder (KTRK)

Police have just released additional surveillance video in connection with the murder of a prominent Houston doctor.

Dr. Mark Hausknecht was gunned down as he rode his bicycle to work in the Texas Medical Center about a week and a half ago.

On Monday, Houston police tweeted out video of the suspect in a nearby neighborhood immediately following the doctor's shooting.

A newly released surveillance video shows the moments before a Houston cardiologist was killed.



ABC13 showed the images of the bike to the owner of Bike Barn, who said while the bike is somewhat common, there are some distinguishing factors.

"It looks like it's something that's either late 80's or early 90's based on the curvature of the fork, which basically attaches the front wheel of the bike to the frame of the bicycle," said Kenton Luff.

Police are still hoping to find more video of the suspect. If you were in the area on the morning of July 20th, investigators are asking that you check your dash cams.

Neighbors are pitching in to help find Dr. Hausknecht's killer. Colman Ryan lives in the area and had signs made.

"What I'm doing is, I'm going to intersections where panhandlers hang out, they're going to be there anyway, so I give them a bottle of Gatorade, a couple of bucks and ask them to display this," said Ryan.

On one side of the sign, it shows a surveillance image of the suspect with a written description of him. On the other side you see the composite sketch.

Ryan doesn't know the doctor but he wanted to help.

"When I saw it on ABC13, I thought what could I do? So, I came up with this idea," said Ryan.

Anyone with information in the killing is urged to contact the Houston Police Department Homicide Unit at 713-308-3600, or Crime Stoppers at 713-222-TIPS.
