THE BRONX - The NYPD is stepping up patrols in the Bronx neighborhood where a 14-year-old boy was killed two weeks ago. 

A mobile command center was set up Monday on East 167th Street and Sheridan Avenue, the same corner where police say Christopher Duran was gunned down while on his way to school. 

Authorities are investigating whether Duran's murder was gang related. 

No arrests have been made.
