SACRAMENTO (CBS13) – Sacramento Mayor Darrell Steinberg said the city is working with police and community leaders to ramp up violence prevention efforts after several shootings – including some that were deadly – occurred throughout the city on Saturday.

In total, three people were killed and nine were injured in four separate shootings that occurred through different parts of Sacramento.

Makaylah Brent, 9, was killed in a drive-by shooting at a Del Paso Heights park that also injured a 6-year-old girl and two adults, one of which was in critical condition.

“It’s heartbreaking to have a child killed and another injured in a senseless act of violence,” Steinberg tweeted Sunday morning. “The escalation of shootings here and across America is unacceptable.”

Makaylah’s family is shocked and hopes something can be done so others don’t have to go through the same pain.

“Mykayla had so much to live for,” said Debra Cummings, Makaylah’s cousin. “I feel sickened to my stomach. I advocate hard day and night to make sure things like this never happens.”

Makaylah was a student in the Twin Rivers Unified School District. In a statement, the district said:

We are heartbroken that one of our Twin Rivers students was fatally injured after shots were fired at a Sacramento park Saturday afternoon. Sadly, another Twin Rivers student, also at the park, was transported to a local hospital and is in stable condition. Both students were enrolled at Allison Elementary School. 

This senseless act of violence has affected all of us in Twin Rivers Unified, and I know you join us in extending our deepest sympathy to the families. Please keep them in your thoughts and prayers.

This is devastating. As a community we must come together to protect our children.

Three other people were injured in a separate shooting that occurred just north of Fairbanks Elementary School. A man was listed in critical condition, but as of Sunday, police said all three victims were stable.

There was no suspect information available for either shooting.

A gunman in the Arden-Arcade area shot three people before taking his own life. Investigators said this shooting appeared to be random.

A 17-year-old boy was found shot and unresponsive after crashing into a pole along Jackson Road, west of Cristo Rey High School near Granite Regional Park. He was pronounced dead at the scene and information regarding a suspect was not available.

The violence continued Sunday as another man was shot just before 2 p.m. along Del Paso Boulevard, just west of the Haggin Oaks Golf Complex.

In response to Steinberg’s statement, Cummings said, “Make sure they have resources in the community so you can trust that they can be okay because you turn your back, look what happens. We can never prepare ourselves for this.”
