A Black Life Matters truck was vandalized in Portland, Oregon overnight last Thursday, setting its owners back upward of $50,000, according to a local report.  

BLM Trucking supervisor Charles Preston told FOX 12 that the venture began in late 2021 to help create jobs for young men and keep them out of trouble.

It’s part of the Golden Opportunity Youth Association and does deliveries for companies like Amazon and Western Pacific. Despite its name, it is not part of the official "Black Lives Matter" organization. 

Founder Timothy Luther McNair said he and Preston parked the truck on Northeast Martin Luther King Jr. Boulevard Thursday night. The next morning, they found it vandalized and torched with profanity spray-painted on the side. 

Preston described seeing the truck as "a dagger in the heart."
