Update, 11 a.m. Monday: Dayan Sanchez surrendered to authorities Monday morning and was taken into custody, police said.

Sanchez, 21, was booked on charges of manslaughter, distribution of marijuana, felony carrying of a firearm by a person convicted of certain felonies, illegal carrying of a firearm while in possession of a controlled substance, illegal discharge of a firearm, and aggravated assault, the Kenner Police Department said in a news release. He will also be booked on probation violations.

Kenner police are still searching for a fourth suspect, who they say conspired and accompanied Hykeem Martin, Deleon “Del” Perrilloux and Tandi Hall to Kenner in order to commit a robbery to acquire marijuana.

Detectives are also searching for a male who accompanied Sanchez to the drug sale.

Sanchez’s bond has not been set. Perrilloux’s bond was set at $175,000 and Hall’s at $100,000.

Original story:

Enisha Martin was getting ready to go to bed about 9:30 p.m. Friday when a St. John the Baptist Parish Sheriff’s Office deputy knocked on her door in Reserve with the news: Her son, Hy’Keem, had been gunned down earlier that day in Kenner.

As the Martin family mourns the loss of the 19-year-old they said was soon to attend college, Kenner police are searching for the man they allege shot him. The police say Martin was killed while trying with three other people to steal drugs from a Kenner marijuana dealer.

Lt. Brian McGregor said Kenner officers responding to a report of a shooting in the 2100 block of 43rd Street in Kenner about 2:45 p.m. Friday found Martin lying dead at the scene.

Not far away, near the Sugar Mill apartments at 4520 Williams Blvd., according to police, officers found 18-year-old Deleon “Del” Perrilloux with a handgun hidden in his pants. Police said they also found Perrilloux’s girlfriend, Tandi Hall, 21, trying to flee the scene in the 4300 block of Idaho Street.

McGregor said the investigation revealed that Perrilloux and Hall had traveled with Martin and a fourth, unknown man from LaPlace to Kenner to steal marijuana from 21-year-old Dayan Sanchez. Martin, Perrilloux and Sanchez were all armed as the encounter began, according to police.

At some point during the transaction, police said, Martin and Sanchez began shooting, and Martin was killed. Police found a gun and marijuana near Martin’s body, according to McGregor.

Police said they have obtained a warrant for the arrest of Sanchez — who is on parole for a February 2015 simple robbery conviction — on counts of manslaughter, distribution of marijuana, carrying of a firearm by a convicted felon, illegal carrying of a firearm while in possession of a controlled substance, illegal discharge of a firearm and aggravated assault.

Sanchez’s last known address, according to police, was just around the corner from the shooting, at 4301 Idaho Ave.

Perrilloux, of Reserve, has been booked on conspiracy to commit armed robbery and illegal carrying of weapons. Hall, of LaPlace, has been booked on conspiracy to commit armed robbery. Both remain in custody.

Martin’s family members, who gathered Sunday afternoon at his mother’s house to console her, said they were shocked by the police account of a drug robbery gone wrong.

“It’s a numbness, because it still seems unreal,” his aunt, Deidra Alexis, 52, said. “Just don’t understand why this happened.”

Relatives said Martin had planned to attend Southeastern Louisiana University. He graduated in 2014 from East St. John High School, where family members said he excelled in drawing.

“Everybody just loved to be around Hy’Keem,” said Enisha Martin, 35. “He was awesome. I don’t know. I’m just lost for words right now.”

Kenner police asked anyone with information on the shooting or Sanchez’s whereabouts to call the department at (504) 712-2222. Detective Vincent Miranti is leading the investigation.
