Two teenagers are facing serious charges after St. John Parish deputies say they robbed a 16-year-old at gunpoint in LaPlace, then in nearby Reserve, on April 4. Deputies allege one of the teens struck the victim with a firearm during the encounter, and both were booked into the parish jail.
What deputies say
According to the St. John the Baptist Parish Sheriff's Office, deputies were called to the 100 block of Dave Street in Reserve at about 5:08 p.m. on April 4 after a report that two people had pointed guns at a 16-year-old. Investigators say the suspects first approached the teen near Elm Street and Fagot Loop in LaPlace, demanded his belongings and ran off with two watches and a pair of headphones valued at roughly $944.
Detectives later executed a search warrant and recovered the headphones and a firearm, according to the sheriff's office. Deputies say they then spotted and detained two people walking on Fagot Loop who matched the description of the suspects.
Arrests and charges
The sheriff’s post includes a reminder that "All persons are presumed innocent until proven guilty," according to the St. John the Baptist Parish Sheriff's Office. The post identifies 18-year-old Jacoi Cosey and 17-year-old Brendell Cosey as the individuals arrested and booked into the parish jail on armed-robbery charges. Brendell was also booked with aggravated battery after allegedly striking the victim with his gun.
Bail was set at $75,000 for Jacoi and $108,000 for Brendell, according to the sheriff's office.
Local context
The arrests are part of a steady stream of public updates from the sheriff’s office about cases in LaPlace. Earlier this year, a LaPlace burglary bust in January drew attention, and local paper L'Observateur has reported other armed-robbery arrests in the parish in recent months. Those outlets say deputies often credit quick patrol response and tips from residents for the arrests, underscoring the role of neighborhood reporting and visible patrols in the area.
