Buffalo police are asking for the public’s help in determining how the driver’s license of a slain taxicab driver was put into a mailbox after his body was discovered Wednesday morning.

Police also are seeking information from anyone who saw Mazen M. Abdallah’s taxicab between 5 and 7 a.m. Wednesday. The vehicle was a white Lincoln Town Car with the number 57 prominently displayed, marked with the Airport Taxi logo.

The vehicle was found in the 700 block of Norfolk Avenue, with the driver’s body in the back seat.

Someone found the victim’s New York State driver’s license, inside a brown leather and plastic insert of a wallet, displaying the victim’s picture and other information. That person may not even have noticed what it was, or its significance, before putting the insert in the mailbox.

Police are asking that person to come forward, with information about where the license was found and the location of the mailbox.

Anyone with any of that information is asked to call the Homicide Squad, at 851-4466, to text a tip at (716) 847-2255, or to visit the department’s website, at
