Cox died from a single gunshot wound to lower part of his back, according to an autopsy performed by Atlantic County Medical Examiner Dr. Eliot Gross.
Authorities said Burgess, 26, of 201B N. New York Ave., who also goes by the name "Sahid," was in critical condition Monday evening at the ACMC, City Division.
He fled from the scene in his car after he was shot and a friend later took him to Shore Memorial Hospital in Somers Point, where authorities found him and later transferred him to ACMC.
Blitz would not comment on what the intruders may have been looking for inside the apartment. When asked if Burleigh's gun was licensed, the prosecutor said that by law individuals do not need permits to keep guns inside their residences.
Robert Mason Sr., a retired postal worker and community activist who lives on Hummock Avenue one house away from the back door of Burleigh's apartment, was sleeping when gunfire woke him up.
"I heard four shots," he said Monday, standing near his front fence, where police found a bloody face mask with a hole in it.
A trail of blood stretched from the back yard where the shooting happened, which is located on Hummock Avenue, to almost a block away, near the corner of Robinson Avenue.
Mason said he stayed inside his house until he saw and heard authorities arrive at the scene.
Police Officers Andrea Perry and Paul Petigna arrived after Kelly, Burleigh's girlfriend, called 911, authorities said.
The North Indiana house is a two-story brick attached dwelling that's owned by city resident Jacqueline Sharpe. The dwelling where the shooting occurred is a three-bedroom duplex. On the other side, at 501 N. Indiana Ave., there's another apartment and a deli.
"I just feel bad that someone's dead," Sharpe said Monday, when reached at her home. "I have no idea what went wrong."
Hummock Avenue resident Sherry Beckam said drug activity has been a problem near the deli in the past.
She peeped out her door at the police activity Monday morning, but didn't go outside.
"That's scary," she said about the slaying.
The crime occurred less than two months after a 15-year-old neighborhood girl was abducted a half-block away at Hummock and Robinson avenues after getting off a school bus.
She was taken out of the city by four male suspects who raped her before dumping her back in the resort.
Monday's incident happened just a short distance from the Atlantic City Convention Center, where thousands of conventioneers later flooded into the area for a refrigeration and heating expo that was billed as the city's largest convention since the 1964 Democratic National Convention.
