Officials in Newark, New Jersey are calling on the suspects behind this weekend's deadly mass shooting to turn themselves in to police. They're asking for the public's help catching them, and are offering a $10,000 reward in the case. 

The gun violence killed 10-year-old Jordan Garcia and 21-year-old Kiyah Mae Scott and injured three other people, including Garcia's 11-year-old bother and Masi Rogers, 19, and Sheppard Miller, 60, according to Essex County prosecutors. 

"This past weekend was a dark weekend in Essex County, in general," Essex County Prosecutor Theodore Stephens II told reporters Monday. 

"Cowardly, heartless and unforgiveable"

So far, there have been no arrests, two days after the brazen shooting rattled the city. 

"It's clear on what needs to happen, that these perpetrators need to turn themselves in immediately -- before the sun goes down tonight, would be preferable -- that you turn yourselves in as soon as possible," Newark Mayor Ras Baraka said Monday, adding, "The community is on alert, on lookout, and we will make sure that justice is done."

Newark Public Safety Director Emanuel Miranda said the department "will not rest" until they catch the suspect, or suspects, responsible. 

"That night was a very tragic night. My heart, condolences go out to the families of the homicide victims," he said. "To hear the yelling and the wailing of those mothers in the hospital is something I will never forget."

The Essex County sheriff's office is offering a reward of up to $10,000 in the case.

"What you did was cowardly, heartless and unforgiveable. You shattered families and shook an entire city. You proved nothing but your own weakness. So hear me clearly, we are coming, there is no hiding, there is no running, there is nothing that will change what's coming. There is no corner of this county, no block, no basement, no friend's couch that will keep you hidden," said Essex County Sheriff Amir Jones.

Learning more about the Newark shooting victims

Surveillance video captured the disturbing timeline of events Saturday night. A group could be seen outside a liquor store on the corner of Leslie Street and Chancellor Avenue, when two gunmen fired multiple shots.

Garcia and Scott were rushed to University Hospital, where they were pronounced dead. Garcia's 11-year-old brother remains hospitalized in stable condition, along with 60-year-old Sheppard Miller, while 19-year-old Masi Rogers is in critical condition, Stephens said. 

Community members rallied around the victims' families Sunday night. Relatives said Garcia was a budding athlete with a love of football. 

"I am trying to be strong"

Scott's mother said her daughter had stepped out to pick something up from a nearby store when she was shot. The family says the 21-year-old leaves behind a child.

"Kiyah was very outgoing, loving to her family and friends," her mother Annette Ryan said. "She loved her son dearly. Very smart, knowledgeable. She had a lot of wisdom. She was very smart." 

Ryan said she's holding on for Kiyah's son. 

"I am trying to be strong for her baby," Ryan said. "I am just concerned about him. He loves his mom." 

The little boy was at home when Ryan got the dreadful news from Scott's friends who ran back from the crime scene. Ryan now has to bury a second daughter after losing one to cancer in 2018. 

What's her message to the shooter?

"You reap what you sow. Everybody has family. You me be the one that may be sitting in my seat one day - your family. Your child," she said. 

"Very difficult as a father, as a man in this city"  

Grief counselors are on hand at Newark public schools Monday, and the superintendent says support will be offered to students and staff this week to cope with the difficult loss. 

Baraka said he visited the victims' families at the hospital over the weekend, and spent the morning with community groups at Chancellor Avenue School. 

"Watching kids come out of the classroom crying was very difficult for me. Very, very difficult as a father, as a man in this city, and very difficult as the mayor," the mayor said. "We've been working tirelessly and endlessly to make sure violence is reduced in the city, but these incidents make clear that there is a lot more work to be done." 

Stephens and Baraka noted the shooting comes against trend, saying the city saw 81 homicides in 2022 compared to 38 so far this year. Authorities have not said whether this shooting was gang related or shared any information on a possible motive.
