The scene punctuated a day of grief, disbelief and anger in the working-class neighborhood in southwest Santa Rosa. By evening, those emotions spilled out onto Moorland Avenue, as hundreds of people marched in a candlelight vigil from the DMV office on Corby Avenue to the site where the boy was killed.
Young teens marched with portraits of the boy, chanting, "We want justice" and "Andy Lopez, Andy Lopez."
The march, which was sparked by a Facebook page, "Justice for Andy Lopez," brought out a number of parents who said they wanted to show their support for Andy's family. Many expressed the same worry — that the same thing could happen to their children.
"I don't know for sure that in the event of an emergency, would the police really help me or jeopardize the safety of my community," said Alma Flores, a mother of three who lives in east Santa Rosa.
"As a mother, it's very painful to imagine that something similar could happen to my 11-year-old son."
The call for "justice" began Wednesday morning, as more people learned that the person who was shot and killed was only 13 years old. Those who knew Andy, a handsome fun-loving boy, expressed disbelief.
Alejandro Cardenas, a Moorland Avenue resident, said he lived next to the Lopez family before they moved to their current home farther south on Moorland near Todd Road. Cardenas, a roofer, had just got off work and was bringing his kids home from school Tuesday when he found his neighborhood entangled in a web of police tape.
"We didn't even know (Andy) was lying out there," said Cardenas, speaking in Spanish.
Lopez's parents, who are originally from the northern Mexican state of Sonora, came to Sonoma County about 20 years ago. Aside from Andy, they have three other children, all of whom were born in the United States.
The family started out in Healdsburg but lived mostly in Santa Rosa.
On Wednesday, friends and family described Lopez as a fun-loving boy with a variety of big dreams, depending on who you asked.
His older brother, Anthony, 17, said Lopez wanted to join the Marines. Luis Diaz, 13, a close friend, said Lopez wanted to become a boxer. Andy's father, Rodrigo, said his son wanted to work for the government.
He played trumpet in the band at Cook Middle School, where he attended classes until this week, and also played saxophone and a little bit of piano at home.
Students and staff at Cook Middle School struggled with news of his death. He was well-known and well-liked on campus, Assistant Principal Linsey Gannon said.
Lopez "was a very popular student, very smart, very capable," Gannon said.
Andy spent seventh grade at Cook and had attended the Sebastopol Road school until Friday. This week, Lopez transferred to Lewis Opportunity School, a small alternative school in the Santa Rosa School District, school officials said.
Grief counselors and therapy dogs were at Cook Middle School on Wednesday morning, part of a crisis intervention plan aimed at helping students and staff, Gannon said.
Evidence of grief and shock was palpable throughout the school.
Some students cried. One collection of students huddled together near the campus flag pole in a large group hug.
Photos of Lopez appeared on an office window. Students taped black-and-white copies of a photo of Andy to their shirts.
