Clarence “Buddy” Mason Modesto Shooting: The 2008 Case That Started With a Bicycle Fall

On April 29, 2008, a late-night walk in Modesto’s Airport District turned deadly after a brief street encounter became a shooting case that would take years to fully resolve.

Stanislaus County prosecutors later said Maurilio Gomez Vasquez became angry after he fell off his bicycle and Clarence “Buddy” Mason and Shawn Tenbrink laughed. According to prosecutors, Vasquez left, threatened to get his “Norteño homies,” then returned with a handgun and shot both men. Mason died, and Tenbrink survived serious injuries.

What Happened To Clarence “Buddy” Mason In Modesto?

The shooting happened in the early morning hours of April 29, 2008, near Kerr and Larkin avenues in Modesto’s Airport District. Modesto Bee reporting said Mason, 51, was walking his dog with a friend when the shooting happened around 2:30 a.m.

At first, the moment may have seemed small. Prosecutors said Vasquez had fallen from his bicycle. Mason and Tenbrink laughed. But that moment quickly turned dangerous.

According to the Stanislaus County District Attorney’s Office, Vasquez became angry, left the area, and later came back with a gun. Prosecutors said he shot both men. Mason died, while Tenbrink was seriously wounded.

Police Said The Victims Were Not Gang Members

Although prosecutors later said the case involved a gang enhancement, police made an important distinction about the victims.

Modesto Bee reporting from the time said police described the victims as not being gang members. Police also said the shooter was believed to be connected to a criminal street gang based on the investigation.

That detail matters because the case was not described as a fight between rival gang members. Instead, public reports described it as a sudden act of violence that followed a brief argument or “respect” issue.

Who Was Clarence “Buddy” Mason?

Family and neighbors knew Clarence Mason as “Buddy.” He had lived in the Airport District for decades and was known around the neighborhood.

According to Modesto Bee reporting, Mason was remembered as a generous person who helped people when he could. Friends said he collected scrap metal, helped tow neighbors’ cars, and often walked his dogs late at night.

After the shooting, family, friends, and neighbors created memorials for Mason. His yellow tow truck became part of that remembrance, covered with flowers and left as a tribute near his home.

The Suspect Fled Before He Was Found Years Later

The case did not end quickly.

Authorities said Vasquez fled to Mexico after the shooting. The Stanislaus County District Attorney’s Office said he was located there in 2012 and extradited back to the United States in 2013.

Modesto Bee reporting said Vasquez was found in Michoacán, Mexico, in a small city called El Tigre. He was later transferred through Mexico City and brought back to Stanislaus County.

How The Case Ended In Court

Years after the shooting, Vasquez pleaded no contest to voluntary manslaughter and assault with a firearm. Prosecutors said he admitted using a firearm and admitted a gang enhancement connected to the shooting.

The final sentence also included a separate jail assault case. Prosecutors said Vasquez pleaded no contest to mayhem and admitted a gang enhancement for a 2014 attack at the Stanislaus County Jail.

In January 2019, Judge Nancy Ashley sentenced Vasquez to 28 years and 4 months in state prison.

Modesto Bee reporting noted that murder and attempted murder charges in the shooting were later dropped as part of the case outcome, while Vasquez pleaded no contest to the reduced charges.

A Modesto Case Still Remembered Years Later

The Clarence “Buddy” Mason case remains one of Modesto’s disturbing late-night crime stories.

A man walking his dog was killed. Another man survived serious injuries. A brief laugh after a bicycle fall became the beginning of a deadly shooting, a years-long search, an extradition from Mexico, and a prison sentence.

More than a decade later, the case is still remembered in Modesto’s crime history because of how quickly one ordinary moment turned into violence.
