A San Francisco jury has convicted 47-year-old Joshua Vasquez of misdemeanor assault and vandalism after he threw a skateboard at a 79-year-old building employee during a dispute over a mailbox, prosecutors announced Thursday. The 79-year-old victim worked for the Tenderloin Neighborhood Development Corporation at the very building where Vasquez lives, and the confrontation played out in the residential lobby on July 14.
According to the KRON4 report on the case, Vasquez became irate after the victim told him he was not authorized to open his mailbox. He then approached the victim and threw a skateboard at him, also damaging property inside the building lobby, prosecutors said. What exactly led up to the confrontation remains unclear, per the outlet's account. The San Francisco District Attorney's Office confirmed the jury reached its verdict on September 10, formally entering the conviction under court number 26016524 for misdemeanor vandalism under California Penal Code § 594(b)(2)(A) and simple assault under Penal Code § 240, according to the San Francisco District Attorney's Office.
Prosecutors Frame the Case as a Message to the Community
Assistant District Attorney Nasser Banihani, who prosecuted the case, said it centers on the mistreatment of people who have dedicated their lives and careers to serving and giving back to the community, per the KRON4 report. DA Brooke Jenkins framed the jury's verdict as sending a message that this kind of behavior will not be tolerated and that the people of San Francisco will not tolerate mistreatment of vulnerable members, the outlet's report notes.
The DA's office credited a broader team with building the case, including paralegals Nohemi Torres and Lord Fernandez, DA Investigators Ted Martin and Perla Ortiz, IT specialist Noaeh Piniare, and investigating officers from the San Francisco Police Department, according to the same office's announcement.
What the Misdemeanor Charges Mean for Vasquez
Simple assault under Penal Code § 240 is a misdemeanor carrying up to six months in county jail and a fine of up to $1,000, according to the Shouse Law Group. The vandalism charge was filed as a misdemeanor.
The conviction is for misdemeanor assault under Penal Code § 240, as described above.
A Case That Falls Short of Elder Abuse Charges
Notably, the case description does not identify a charge under California's elder abuse statute, Penal Code § 368, which criminalizes willfully inflicting unjustifiable physical pain or mental suffering on people 65 or older and allows prosecutors to file either misdemeanor or felony counts, per Shouse Law Group. That statute is distinct from the vandalism and simple-assault provisions cited in the convictions.
DA Jenkins established a dedicated Vulnerable Victims Unit in September 2022 to handle prosecutions of elder abuse, hate crimes, and physical attacks targeting senior citizens, according to the San Francisco District Attorney's Office. That specialized structure exists alongside broader budget pressures on victim support: DA Jenkins reported to city leaders in February 2025 that the office faced proposed reductions, per SF.gov records.
