A man who was found guilty of painting swastikas and anti-Semitic graffiti on a San Fernando Valley business was sentenced to three years in jail, the Los Angeles City Attorney’s Office announced.

Amos Hason, 49, was found guilty of three counts of vandalism and three counts of a hate crime against a Jewish business owner in Van Nuys and was sentenced Friday, said City Attorney Mike Feuer in a statement.

Prosecutors said Hason was involved in several acts of vandalism and hate crimes against the same business owner. Hason was identified in video surveillance in two separate incidents in April. He drove to the location and painted swastikas and anti-Semitic graffiti on the rear fence and dumpster behind a Van Nuys plumbing business.

Hason left the message “Adolf was right. Kill Jews!” with a swastika at the end. Hason had never met the business owner, according to the City Attorney’s Office. Charges were filed against Hason in May.

“Hate crimes will not be tolerated in this city and my office will continue to take swift and decisive action whenever these incidents occur,” Feuer said.

The City Attorney’s Office had prosecuted Hason twice before. In 2013 he was convicted for possession of a zip gun, a homemade firearm and in 2008 was found guilty of possessing a deadly weapon with the intent to assault another.
