It was the third law-enforcement related shooting in Newark in a week and the fifth in the past month.

The prosecutor’s office is investigating and has so far only said that the officer encountered Gaymon when he was dispatched to the scene after complaints about sexual activity in public. Authorities are not saying what precipitated the shooting and Gaymon did not appear to be armed.

The undercover sheriff’s detective has not yet provided a full statement to investigators.

Gaymon had spent a year organizing his Montclair High School class of 1980 reunion, which took place at the Crowne Plaza Hotel in the Meadowlands that evening. Bari Belosa, the owner of Reunions Unlimited of Englishtown, helped Gaymon organize the event.

“He was a gentleman. Lovely. He was a very kind, very respectful man,” Belosa said today. “Very easy to deal with.”

Gaymon, who was married with two daughters and two sons, had traveled to New Jersey Thursday night, said his sister, Kelly Gaymon Armstrong. She said her brother lived for several years in Columbia, S.C., where he was vice president of a credit union there.

“He worked his way up,” she said. Gaymon moved to the Atlanta area six years ago with his family.

Kelly Gaymon Armstrong said her family spoke with someone from the prosecutor’s office today, but still doesn’t know what happened. “This family is destroyed,” she said. “we want answers.”
