Richard Olango said he started the foundation to honor his late son.
Alfred Olango was killed by police earlier this week.
El Cajon Mayor Bill Wells identified one of the officers as Richard Gonsalves.
Protesters earlier in the day shouted “murder” and demanded a federal investigation into the killing.
“He had a lion’s heart. He loved too much," his brother said.
Police say that the man assumed a "shooting stance" after pulling out the vape pen.
The man later died after being taken to the hospital.
