They Urinated on a Sleeping Homeless Man and Beat Him Into a Permanent Brain Injury.
A California Judge Gave Them Zero Days in Prison.
At around 1:30 a.m. on March 20, 2026, prosecutors say Boaz Winslow Brigham, 21, and Malachy Damien Hayes, 18, came across Douglas Mark asleep in Elm Street Park in Arroyo Grande, on California’s Central Coast. Hayes urinated on Mark while he slept. Then, according to the San Luis Obispo County District Attorney’s Office, both men punched and kicked him in the head, face, and body — while Brigham filmed the beating on his phone. Investigators say the two were captured on video afterward laughing and high-fiving, and that Brigham shared the recording on Snapchat.
Mark survived. He did not survive intact: prosecutors say the beating left him with a permanent traumatic brain injury, broken ribs, and memory problems that persist today. Both defendants pleaded guilty or no contest to felony elder abuse with a great-bodily-injury enhancement — a strike under California’s Three Strikes law — and District Attorney Dan Dow asked the court for the statutory maximum of seven years in state prison.
On July 13, 2026, San Luis Obispo County Superior Court Judge Crystal Tindell Seiler suspended a five-year prison sentence and ordered 364 days in county jail, four years of probation, and a four-year ban on social media instead. Neither man will serve a single day in state prison.

According to the San Luis Obispo County District Attorney’s Office, the assault unfolded in the span of about fifteen minutes, between 1:30 and 1:45 a.m. on March 20, 2026. Douglas Mark, homeless, was asleep in Elm Street Park when Brigham and Hayes approached him. Hayes urinated on Mark as he lay sleeping. What followed, prosecutors say, was not a single blow struck in anger but a sustained beating: both men punched and kicked Mark repeatedly in the head, face, and body while he was defenseless and unable to fight back.
Brigham recorded the assault on his phone and later shared the video through Snapchat, according to the DA’s office. Investigators say footage also shows the two men laughing and high-fiving one another once the beating stopped — a detail prosecutors cited directly in describing the attack as predatory rather than a fight that got out of hand. Arroyo Grande police arrested Brigham and Hayes on April 9, 2026, nearly three weeks after the assault.
Mark’s injuries did not resolve when the bruises healed. The San Luis Obispo County DA’s office says the beating left him with a permanent traumatic brain injury and broken ribs, and that he continues to struggle with memory problems months later. At the July 13 sentencing hearing, Mark delivered a victim-impact statement describing a case that is finished on paper and a recovery that is not.
“They ruined my brain. My brain is broken.”

“For this to be considered probation is outrageous,” Mark told the court. He is not a defendant in this case and carries no legal burden here; he is the man both prosecutors and the court agree was beaten while he slept, on video, and left permanently injured.
Brigham and Hayes were each charged with felony elder abuse carrying a great-bodily-injury enhancement — a charge that also counts as a strike under California’s Three Strikes law. Both entered pleas of guilty or no contest rather than take the case to trial. In announcing the case, District Attorney Dan Dow described what happened to Mark in blunt terms.
“This elderly man was homeless, asleep, and completely defenseless when he was humiliated and brutally beaten, leaving him with a permanent brain injury.”
District Attorney Dan Dow, San Luis Obispo County, official statement
Dow’s office asked the court to impose the statutory maximum: seven years in state prison for a case prosecutors called a predatory, recorded attack on a sleeping victim. Under California’s sentencing framework, a felony elder-abuse conviction with a great-bodily-injury enhancement carries a presumption in favor of state prison over probation — a presumption a judge can depart from only for a stated reason on the record.
On July 13, 2026, Judge Crystal Tindell Seiler departed from that presumption. She suspended a five-year prison sentence for each defendant and instead ordered 364 days in county jail, four years of probation, and a four-year ban on social media use. Because the underlying prison term was suspended rather than imposed, neither Brigham nor Hayes will serve a day in state prison for an attack prosecutors describe as leaving a sleeping, defenseless man with permanent brain damage.
“[The presumption favoring prison] was overcome by each defendant's youth, lack of significant prior criminal history, and willingness to accept responsibility by pleading to the charges.”
The court's stated sentencing rationale, per KEYT reporting, July 15, 2026
The judge — Crystal Tindell Seiler, appointed to the San Luis Obispo County Superior Court bench by Gov. Gavin Newsom (D-CA) in July 2023, promoted from the county’s own Deputy District Attorney’s office. Seiler is registered with no party preference, per Ballotpedia — but the appointment itself is a Newsom (D) judicial pick.
The prosecutor — District Attorney Dan Dow, who sought the statutory maximum of seven years and publicly criticized the outcome. Dow is a U.S. Army Colonel who received a Bronze Star for service in Iraq, and ran as a Republican for the California State Assembly in 2002.
The county — San Luis Obispo County, on California’s Central Coast, where the case was charged and resolved in Superior Court.
Dow did not stay quiet after the ruling. His office issued a statement making clear the DA’s position was overridden, not shared.
“We sought a state prison sentence because this predatory, recorded attack on a sleeping victim warranted the strongest response the law allows. Although we are disappointed that probation was granted instead of prison, we respect the Court's authority and will continue to stand with victims and advocate for firm, just consequences for violent offenders.”
District Attorney Dan Dow, statement on the sentencing, July 2026
Two men urinated on a sleeping homeless man, beat him with enough force to cause a permanent brain injury, filmed it, and shared the video for laughs. Prosecutors asked for the seven years state law allows. A judge appointed by Gov. Gavin Newsom (D-CA) gave them 364 days in county jail, probation, and a social-media ban instead — and both men go home. Douglas Mark does not get his memory back.
