San Diego sheriff’s deputies charged with misdemeanor assault in violent arrest

Two deputies are facing criminal charges in connection with a violent arrest in Vista that was captured by a neighbor’s video camera nearly seven months ago, the San Diego County district attorney’s office announced Tuesday.

Deputy Nicholas Morgan, 27, was charged with two counts of misdemeanor assault without lawful necessity by an officer. Prosecutors allege that Morgan assaulted a man and his father during a May arrest. He faces up to two years in jail if convicted.

Deputy Joshua Nahan, 31, is facing one misdemeanor count of assault without lawful necessity by an officer for allegedly assaulting the older man. He faces up to a year in jail if convicted.

The two deputies, who are on paid administrative leave, are slated to be arraigned Friday morning in Vista.


“Law enforcement officers hold a position of trust in our community and are required to abide by the rules in the exercise of their powers.” Dist. Atty. Summer Stephan said in a statement. “The evidence on which the charges are based shows the force used by the two deputies exceeded the legal line, violating that public trust. For justice to thrive, it is important that no one is above the law.”

Shortly after the charges were formally announced, community advocates gathered at a news conference outside the Vista sheriff’s station. Many said they were thankful to see charges filed but wanted to see them brought in other cases in which they allege criminal behavior under color of authority.

“They feel like this crumb is not enough — I am starving,” said Yusef Miller with the San Diego office of the Council on American-Islamic Relations, or CAIR.

The May 7 encounter with authorities grabbed attention after a bystander shot video of the waning seconds of the arrest of a father and son.


The 22-second recording appeared to show deputies manhandling Gerardo Martinez Sr., 50, and his namesake son after they were in handcuffs.

The footage showed Martinez Sr. shoved into a wooden fence face first. His 24-year-old son, pinned to a sidewalk, was struck repeatedly in the head.

A neighbor shot the recording. The sister and daughter of the men in the video posted it on social media. There, it quickly picked up steam and garnered media coverage.

On Tuesday, the Sheriff’s Department issued a statement saying that it learned of the video the day after the arrest and immediately opened an internal investigation, which it said was “comprehensive” and included reviewing video from the deputies’ body cameras as well as reports and interviews with everyone involved.


“The department does not tolerate misconduct of any kind,” the Sheriff’s Department said.

After the arrest, the district attorney’s office dropped all charges against the elder Martinez and dismissed a resisting-arrest charge against his son. However, in July, the son pleaded guilty to a domestic violence-related charge and was sentenced to four years of probation.
