Police are looking for a man who was seen on camera attacking a another man who later collapsed at his job. FOX 26's Leslie DelasBour spoke to Houston Police and concerned residents.

The backstory:

Anival Patricio Elvir Ortiz, 77, was biking on a trail in Second Ward near Canal Street when he was attacked and stabbed just before 6 a.m. Aug. 7. The incident was caught on surveillance footage.

Houston police say it’s about a 10-to-15-minute ride from where Ortiz was stabbed to his place of work, where he collapsed. 

"He rode all the way to work. He collapsed at work. They called an ambulance, and he passed away at Memorial Herman Hospital," said Detective Sgt. Mark Holbrook. "He might not have realized his injuries were so severe, and he just kept riding his bike, and eventually he succumbed to his injuries." 

HPD says the suspect left the area and was seen going south on Lockwood that morning. Police shared video of a suspect at a METRO Rail stop last week and asked for the public's help to identify him.
