Hispanic group has heavy presence in New Brunswick, according to police.

   Graffiti that recently popped up on fence outside a Witherspoon Street mixed-use building in Princeton Borough has gang connotations.
   Princeton Borough Police Lt. Dennis McManimon said police officers took photos of the graffiti and sent the images to the New Jersey State Police Street Gang Unit for analysis.
   "We got an e-mail back that the graffiti is for a gang, the La Mugre, which means 'The Dirt,'" Lt. McManimon said.
   The street gang is made up of Hispanic members and is a rival of the 18th Street Mexican Gang, also with a Hispanic membership, Lt. McManimon said. Both gangs have a heavy presence in New Brunswick, he said.
   "We will be keeping an eye on it," Lt. McManimon added.
   In the late fall of 2001, 11 incidents of graffiti using the insignia of the Latin Kings and the 18th Street Mexican Gang — both Hispanic gangs from California — were found on buildings and other property along Nassau Street between Tulane Street and Moran Avenue, according to police.
   Other incidents involving Princeton teenagers last fall raised community concerns about street gang activity in the two Princetons.
   Richard Wilson, 17, a borough resident and Princeton High School student, was shot Dec. 12 as he and a friend, a former Princeton resident, were leaving a Trenton deli. Trenton police have not said if the incident was gang-related.
   In late September, 18-year-old borough resident Jean Mario Israel was shot and killed in a Trenton park in what police described as a gang-related incident. Mr. Israel, who had attended Princeton High School but was not enrolled at the time of the incident, was apparently shot over a debt of several hundred dollars owed by a friend, police said at the time. Mr. Israel's funeral in the borough was attended by numerous gang members.
