BROCKTON – The man suspected of fatally shooting two teens in Brockton has been captured in Mexico, Plymouth County District Attorney Timothy J. Cruz and Acting U.S. Marshal Dennis Matulewicz for the District of Massachusetts have announced.

Davinci Leonard, now 23, was wanted for a double homicide in Brockton, and stands charged with two counts of Murder, and one count each of Discharging a Firearm within 500 feet of a Dwelling, Carrying a Loaded Firearm Without a License, and Carrying Ammunition without an FID card. Leonard is accused of killing 15-year-old Tymari Albertson and 18-year-old Cevannah Alvarez.

On Thursday, at approximately 1:30 PT, the U.S. Marshals  of the Southern District of California Mexico Investigative Liaison team along with the San Diego Fugitive Task Force coordinated and facilitated the apprehension of Leonard with Fuerza Estatal de Seguridad Ciudadana (FESC). Leonard was expelled back to the United States and into the custody of the U.S. Marshals Service, where he will then be transported back to Massachusetts for his arraignment in Brockton District Court.  

On March 22, 2025, at approximately 7:04 p.m., Brockton Police received a 911 call for a report of a shooting outside the Chipotle located at 500 Westgate Drive. Upon arrival, first responders located two victims, a male and a female, suffering from gunshot wounds. Both were transported to Good Samaritan Hospital. The male victim was pronounced deceased at the hospital. He was identified as Albertson. The female victim was medflighted to Massachusetts General Hospital where she succumbed to her injuries. She was identified as Alvarez.

Leonard fled the scene, and since that day authorities have been searching for him and gathering information about his whereabouts. The extensive investigation by Massachusetts State Police, the MSP Violent Fugitive Apprehension Section, and the Brockton Police, included numerous witness interviews, a review of video surveillance footage, and an extensive canvass of the scene. Investigators developed information and sought and obtained an arrest warrant for Leonard. The Commonwealth Fusion Center composed a BOLO bulletin that was distributed to area-wide law enforcement agencies.

David Mosley-Lott, 32, of Quincy and Jaylen Speed, 25, of Dorchester have been indicted on charges in the double homicide for their alleged involvement in helping Leonard evade justice. Mosley-Lott is charged with one count each of Accessory After the Fact and Intimidation of a Witness, while Speed is charged with one count of Accessory After the Fact.

DA Cruz said, “A lot of work was put into this case by troopers assigned to our Detective Unit, the MSP Violent Fugitive Apprehension Section, and our federal partners at the U.S. Marshals. This was a lengthy and thorough investigation which took officers up and down the east coast, west to Michigan and California, and then on to Haiti, and ultimately to Mexico. I commend all those involved for their hard work and determination on this case.”
