Jefferson Parish authorities have arrested one man and continue to search for a second in connection with the carjacking of a woman and her teenage daughter Saturday in Metairie.

Antonio Marcelin, 19, of New Orleans was booked as an accessory after the fact to armed robbery in the carjacking that occurred in the 600 block of Bonnabel Boulevard, near Interstate 10.

A warrant for two counts of armed robbery has been issued for 18-year-old Hendrick Porter, whose last known address is in the 1800 block of Estalote Street in Harvey.

The victim at first told investigators that the suspects jumped in front of her car as she and her 14-year-old daughter drove north on Bonnabel.

Investigators later determined that the victims actually passed up the suspects and then made a U-turn to try to help what appeared to be people who needed roadside help, said Col. John Fortunato, a Jefferson Parish Sheriff’s Office spokesman.

The victims’ 2008 Chevrolet Cobalt was seen on surveillance footage pulled up behind the suspects’ 1997 Ford Explorer, which was left behind after the men allegedly stole the Cobalt.

Investigators found fingerprints and other evidence in the Explorer that led them to identify Marcelin as a suspect.

Marcelin, who owns the Explorer, first told detectives that someone had stolen the SUV, but detectives said they noted inconsistencies in his story.

He told them that on Saturday he was in Algiers when two men known only to him as “Ace” or “Anthony” and “J” or “Jonathan” asked him for a ride to Kenner. While on the way there, he said, the vehicle began to overheat and he exited Interstate 10 at Bonnabel.

Marcelin said he told “Ace” and “J” he was going to look for help and the men stayed in the SUV. When he went back to the 600 block of Bonnabel, he said, his SUV was no longer there.

He told detectives that he somehow made his way back to the West Bank and assumed “Ace”and “J” would return his SUV.

After Sgt. Kevin Balser pointed out “several improbabilities” in Marcelin’s story, Fortunato said, Marcelin admitted he lied about the theft.

Marcelin claimed “Ace” and “J” began to panic because they were in Jefferson Parish and had a handgun and an AK-47 rifle.

He said that when the SUV would not start, “Ace” and “J” told him something had to be done to get them out of the area.

“J” tried to flag down a ride, leading the woman in the Cobalt to turn around.

Marcelin said “Ace” and “J” walked up to the car and took it at gunpoint.

The vehicle, he said, was dumped at the Jackson Landing apartments in Algiers. Fortunato said it was recovered Tuesday.

Marcelin later told Balser that he lied about the names of the people in the vehicle, admitting one of the armed men was someone he knew as “Lil Hen,” or Porter.

Investigators continue to try to identify the other man in the incident, Fortunato said.

Anyone with information on the whereabouts of Porter is asked to contact Detective Kevin Balser at (504) 364-5300 or Crimestoppers at (504) 822-1111.
