San Jose police have arrested a 20-year-old Vallejo native suspected of gunning down two former Bay Area high school football players in separate shootings roughly a year apart, ending a manhunt that stretched across two counties. Adonnis Evans, who also raps under the stage name Lul Dada, was booked into Solano County jail on suspicion of fatally shooting 19-year-old Ta'Marcus Williams outside a Fairfield smoke shop last August, and investigators have also named him a primary suspect in the unsolved June 2025 killing of 18-year-old Guardian Harper at a Bay Point house party.
Williams, an Armijo High graduate, was shot through the passenger window of a parked Kia on the 1300 block of West Texas Street around 8:30 PM on August 8, 2025, while Evans' girlfriend was inside the smoke shop buying corn chips, according to Pressbee. Williams died inside the vehicle before emergency responders arrived, and police say Evans and his girlfriend then fled south toward San Jose in a waiting Nissan. Solano County prosecutors filed murder and firearm charges against Evans on August 22, 2025, but he evaded capture for nearly a year before his arrest this week, as reported by The Mercury News. He is expected to be arraigned next week and cannot be bailed out of jail.
The Armijo Royals football program remembered Williams on Facebook as more than just a player and a member of the team's family, adding that he brought laughter to the locker room and big tackles on the field, per the Mercury News report.
A Second Killing Tied Back to Evans
Months before the Fairfield shooting, Harper was killed on the front lawn of a Bay Point house party around midnight on June 15, 2025, when two masked gunmen opened fire on guests as they were leaving. Two women ducked behind Harper for cover and were injured, according to Pressbee's account of the shooting, which broke out after a party guest accused others of stealing a lost phone.
Investigators say they linked Evans to Harper's killing using cellphone location records, telematics data pulled from a getaway Kia, recorded jail calls, and social media video posts, per the same Pressbee report. Formal charges in Harper's death have not been filed, and the Mercury News notes that Evans has not been charged in that killing even after his arrest this week.
Harper, a 2024 El Cerrito High graduate and former Bay Area News Group Athlete of the Week, played football at both Benicia and El Cerrito High Schools before moving on to American River College and San Francisco City College. He had appeared in the North Coast Section Division II championship game at Diablo Valley College in Pleasant Hill in November 2023, where he was pictured celebrating with teammate Rashad Fontenot, the Mercury News reported.
Jail Calls, Rap Lyrics and Threats to a YouTuber
According to Pressbee, Evans was recorded on a jail phone call hours after Harper's death, declaring “I play offense” and saying he planned to get a new teardrop tattoo — a symbol associated with homicide that he later referenced in a February 2026 rap song called “Wearing Bodies.” Evans continued producing music under the Lul Dada name throughout his year as a fugitive, releasing tracks through the 200 Records label that referenced homicides and gang rivalries, per Shazam's listing of his catalog.
While evading law enforcement, Evans allegedly threatened the creator behind Swamp Storiez, a YouTube channel that covers Bay Area crime, after it posted a video discussing the killings of both Harper and Williams. The channel told The Mercury News that the suspect threatened to put you on a (memorial) t-shirt. The Swamp Storiez later removed the video from its channel.
A Gang Feud Investigators Say Runs Through Vallejo
Police attributed the motive behind the killings to a rivalry between Vallejo's Country Club Crest gang and a rival group, according to the Mercury News, with Pressbee identifying that rival as $hred Money, a West Vallejo-based gang. One of Harper's relatives was allegedly a member of the rival group, according to the Mercury News report, and Pressbee notes that retaliatory shootings followed in Oakland and Vallejo shortly after Harper's death.
The gang tensions playing out across Contra Costa and Solano counties mirror struggles closer to home for Vallejo. A public records review published by Vallejo Sun in June found that the city's violence intervention efforts, including a $700,000 grant awarded to the nonprofit Advance Peace, have faced persistent communication and data-sharing hurdles with the Vallejo Police Department, even as gun battles continued in neighborhoods like Country Club Crest.
It remains unclear what led San Jose police to Evans' location after a year on the run, and whether Contra Costa County prosecutors will now move to file charges against him in Harper's death. For now, Evans faces arraignment next week in Solano County on the murder and firearm charges tied to Williams' killing.
