FT. LAUDERDALE (CBSMiami) – Ft. Lauderdale police have taken two people into custody in connection with the murder of a man last month who was described by his friends as the ‘eyes and ears’ of the neighborhood.

Volvick Vassor Jr., 19, and Christlepher Zetrenne, 18, have each been charged with one count of murder in the death of 66-year old Nelson Heck who was gunned down in the front door way of his residence in the 1100 block of NW 48th Street on Nov. 15th.  Police confirmed that Vassor and Zetrenne were both students at Northeast High School in Oakland Park.

Detectives believe there may be more suspects, currently at large, involved in the homicide.

On the night Heck died, neighbors called police just after 11 p.m. to report the sound of gunfire.  Jorge Manresa told CBS4 that he heard “pop” sounds and then saw a car speed away. That’s when he saw Heck’s body lying in front of his doorway.

Neighbors were stunned and saddened by Heck’s death.

“He looked out for his neighbors, always there to help everyone,” said a tearful Lynne Davis.

Heck, who was a Vietnam veteran, had retired recently from his job at Florida Power and Light.

Investigators believe Heck got into some sort of dispute with another man, or men, and it was during this confrontation that he was shot. During the argument, detectives believe Heck got his own gun and fired back before he was killed.
