But friends of Lopez who marched for hours through downtown Santa Rosa shouting "No justice, no peace!" said a veteran officer should have recognized that the object in Lopez's left hand was a BB gun.
"He should have known. He is a sheriff. He should have known that it was a fake," Carmona said.
Friday's march began around 10a.m. and stretched from points on Sebastopol Road to City Hall, where people rallied and encouraged passers-by to honk. Just before noon, the crowd headed north on Mendocino Avenue toward the Sheriff's Office on Ventura Avenue.
"We are here to support the family and to show Andy we are going to get justice for him," said Maria Arreguin, an Elsie Allen ninth-grader who had known Lopez since the second grade at Bellevue Elementary School.
She said the deputies responsible "deserve to get fired and be in jail."
The deputy who shot Lopez is a 24-year veteran of the force who works as a training officer. His partner on Tuesday had been hired recently by the Sheriff's Office and had 11years experience in law enforcement. He did not fire his weapon.
Sheriff's and police officials have not released the name of either deputy, citing fear for their safety.
Luis Diaz, the 13-year-old boy to whose home Lopez was headed when he was killed, wore a white hooded sweatshirt with a photo of his friend on the front.
"What if that happened to their kids?" he said of the deputies.
"A lot of people are angry about this. It's a friend. I feel it, too. We have a lot of emotion now," said Elsie Allen freshman Yaritza Ramirez as she walked down Sebastopol Road carrying a sign saying Lopez would always be in her heart.
