One man fatally shot another man at the shooter's apartment in Marrero on Monday and then dumped the body in Gonzales with the help of his roommate and a woman, the Jefferson Parish Sheriff's Office said Wednesday.

Investigators jailed Archie Armstrong, 20, on one count of second-degree murder Tuesday in the slaying of Francisco Nieves, also 20, of Gretna, Sheriff Joe Lopinto said at a news conference.

Armstrong's roommate, 21-year-old Vernell Wilson, and Stefanie Enciso, 31, of Covington, were booked on counts of obstruction of justice and being accessories after the fact to murder.

According to Lopinto, investigators probing the first murder of the year in Jefferson believe Nieves was shot to death Monday at an apartment shared by Armstrong and Wilson in the 1500 block of Avenue A.

Nieves' corpse was then taken to Gonzales in Ascension Parish and discarded, Lopinto said.

It is not clear why Nieves was slain, said Lopinto, who added that the victim knew the three suspects but declined to delve into details. 

Nieves' godmother, Jeanette Perez, said in a telephone interview Wednesday night that she understood her godson had dated and lived with Enciso and was friends with the other two men. 

Lopinto said his office became aware of the killing early Tuesday when an unidentified "cooperating witness" contacted the agency just after midnight and informed it of Nieves' fate.

Police officers in Gonzales discovered Nieves' body later Tuesday in a ditch in a clearing between Verna Street and a nearby trailer park, authorities said. He had been shot multiple times and had no identification on him.

After Nieves' identity was confirmed, Lopinto said, the Sheriff's Office took Armstrong and Wilson into custody.

As the investigation progressed, the agency later also picked up Enciso. She previously lived in Abita Springs and Lower Burrell, Pennsylvania, before moving to Covington, public records show.

Aside from the counts connected with the Nieves case, Wilson and Armstrong also face allegations of illegally possessing stolen firearms and being felons illegally carrying weapons, plus unrelated outstanding warrants.

Deputies additionally allege that Armstrong was illegally possessing marijuana and was on parole at the time they arrested him.

Conviction of second-degree murder carries mandatory life imprisonment in Louisiana.

Bail for Armstrong and Wilson was set at more than $1.2 million and $525,000, respectively, though they were ordered held on no bail on some of the counts not related to their arrests Tuesday.

Enciso's bail was set at $350,000.

According to information available on social media, Nieves attended West Jefferson High School in Harvey. Perez said his survivors include his parents, two brothers and a sister. 

"He was a good kid," Perez said. "If he could help you out, he would help you out."
