ST. LOUIS – A St. Louis man serving 40 years in federal prison for two carjackings, one of which was fatal, has been charged for a separate fatal carjacking 17 hours earlier.

Loyse Dozier III, 22, pleaded guilty in December 2023 to four felony counts: carjacking resulting in death, attempted carjacking resulting in serious bodily injury, being a felon in possession of a firearm, and possession with intent to distribute fentanyl. He was sentenced in March 2024.

On Wednesday, Dec. 11, 2024, the St. Louis Circuit Attorney's Office charged Dozier with first-degree murder, first-degree robbery, unlawful possession of a firearm, and two counts of armed criminal action for a fatal carjacking on July 9, 2022.

That carjacking took place around 11:40 p.m. in the 4200 block of North Grand Boulevard in the Fairground neighborhood, according to court documents obtained by FOX 2 News.

Police said Dozier was riding in Montez Haines' vehicle. Surveillance video shows the vehicle pulling up at the curb on North Grand and Dozier shooting Haines while they were both still in the car. Haines can be seen stumbling out of the car as Dozier exits the passenger side, walks around the vehicle, and shoots Haines again. Dozier took Haines' keys and drove off in the vehicle. Haines died at the scene. He was 38.

No court date has been announced by the St. Louis Circuit Court as Dozier is already imprisoned.

The following afternoon, Dozier shot and killed Laruth Jones at the Raqqa Food Mart, located in the 300 block of Chambers Road in Riverview.

Jones was standing near the store entrance when she saw Dozier, who was wearing a full face mask, enter her Mercedes CLA 250. Jones, who was armed, went out to confront Dozier.

Dozier and Jones exchanged gunfire, and Jones was killed. She was 34.

Dozier took Jones’ firearm and fled in the stolen Mercedes. The vehicle was later found torched in a St. Louis alley.

On Aug. 1, 2022, Dozier shot a woman three times during a carjacking outside a Walgreens in the 1400 block of North Grand Boulevard.

In that incident, the victim was sitting in her car, a Kia Optima, when Dozier, who was masked and armed, walked up to the vehicle and demanded the woman’s keys. The victim complied and handed over her keys.

Dozier shot her twice before getting into the car.

An off-duty Florissant police officer was working security inside the store when he heard the gunshots and ran outside. Dozier got out of the car and ran off but left his phone in the Kia.

Nine days later, officers with the St. Louis Metropolitan Police Department saw Dozier at a gas station at West Florissant and Adelaide avenues. He ran off and attempted to discard a handgun and a bag containing 5.76 grams of fentanyl.

That firearm he’d attempted to discard was a .45-caliber Smith & Wesson handgun, which he’d stolen from Jones after killing her. That same weapon was used in the third carjacking and shooting.
