An off-duty New Orleans police officer has been killed in a shooting at a restaurant in Houston that also left another man critically wounded. Houston Police Chief Troy Finner hopes someone will come forward with information that could help track down the suspects. Police say the victims were dining outdoors at the restaurant when the two suspects walked up, started robbing the patrons and then shot the two men. The victims' names have not been released. New Orleans Police Department Superintendent Shaun Ferguson said they had been made aware of the incident and are praying for the family of the fallen officer and the family of the second victim involved.
