SAN ANTONIO-Crime Stoppers is now offering a cash reward for information about a crash that killed a deputy constable last August. Sgt. Mark Scianna died in the accident Aug. 27, 2011 at Lockhill Selma and George Road, off Northwest Military Highway.
Investigators say Sgt. Scianna had his lights and siren on in a short, high-speed pursuit moments before the crash. He was ejected from his unmarked patrol car and died at the scene.
No one has been arrested in connection with his death.
"We know the persons or person being pursued did not stop and render aid. We know there are people who know the identity of the people out there. We are asking the community for help to provide that information to Crime Stoppers," Bexar County Precinct 3 Constable Mark Vojvodich said.
Vojvodich his department has received partial descriptions about the vehicle involved in the chase, but he is not releasing that information.
Sgt. Stanley Davies was Sgt. Scianna's protege.
"We constantly joked he was the honey badger. He didn't care. He did everything by the book," Sgt. Davies said. He praised his friend's work ethic and said Sgt. Scianna was even respected by criminals in the area.
"He was the one that wore the Superman on his chest and as far as we were concerned, he had no Kryptonite," Sgt. Davies said.
49-year-old Sgt. Scianna left behind a teenage special needs son, Christopher.
"I got to spend a lot of time with Christopher in Washington D.C. for the Law Officers Memorial. I was his escort," Sgt. Davies explained. He said following President Obama's speech, he wasn't prepared to stop and take pictures but he made time to snap a quick photo with Christopher.
"That was a very proud moment for Chris," Sgt. Davies said.
Even more painful than Sgt. Scianna's death is wondering why and how it happened, Sgt. Davies said. Vojvodich said Sgt. Scianna did not have time to radio dispatch about the pursuit and he did not have a camera in his patrol car. Sgt. Scianna was following protocol at the time of his death, he said.
Crime Stoppers is offering up to a $5,000 reward and the precinct 3 office is offering an additional $1,000. If you have any information that could help investigators, call 224-STOP. You can remain anonymous.
