'Justice for Joe' was the theme of a gathering of family and friends of 51-year-old Joe Bell. A year ago he died after being shot during lunch time at Church's Chicken in York.
"To all officials we demand of you to present the truth and nothing else," said Bell's son.
Earlier this year the man who was chief of police in York at the time of the shooting pleaded not guilty to manslaughter.
With a trial yet to be held, Bell's family members say all they want is justice but have doubts about whether it will come.
"I'll be glad when it gets over with, but we know it's going to be another sad occasion. We know that we won't get no justice," said Bell's widow, Elizabeth Bell. "With a manslaughter charge, that wasn't no justice."
The case is expected to go trial in November. If found guilty, Rowry could face from 10 to 20 years in prison.
