A foster child was injured while being cared for by the North Las Vegas family at the center of an investigation into a missing 2 1/2-year-old girl, Clark County officials confirmed Thursday.

County officials reviewed the injury to the child, who was being cared for by foster parents Manuel and Vilma Carrascal, but "deemed it unintentional," said Gina Olivares, a spokeswoman for Clark County.

"The child was not removed from the home due to any injury," said Olivares, who wouldn't discuss specifics about the injury, including the date that it occurred, citing state law.

In the ongoing investigation involving the Carrascals, 2 1/2-year-old Everlyse Cabrera was reported missing about noon Saturday.

Sometime after 1 a.m., Everlyse used a stool to climb up to and unlock a deadbolt on the front door and leave the foster home where she was living in the 6500 block of Diamond Point Court, near Centennial Parkway and Clayton Street, the foster parents initially told North Las Vegas police.

The foster family has since stopped cooperating with the police investigation.

Investigators are looking at five scenarios to explain Everlyse's disappearance: She walked away on her own; she walked out of the foster home and was abducted by someone; someone came into the home and abducted the girl; she was abducted by a relative; or something happened to her inside the foster home.

North Las Vegas police spokesman Tim Bedwell repeated Thursday that the foster family are not suspects and are welcome to talk with authorities at any time.

Meanwhile, neighbors picketed and shouted at the foster family's home on Thursday evening demanding they "stop hiding" Everlyse.

"You are the foster family, and you are the only people who are not helping," one protester yelled at the home. "Don't you have feelings?"

The 10 protesters carried signs saying, "Pray for Everlyse" and "CPS (child protective services) failed Everlyse."

At one point the group yelled in unison, "We want answers. We want answers."

Police officers watched as the protesters huddled around Everlyse's mother, Marlena Olivas, who led the group in a prayer.

"We are not going away. We need to remember she will be found," Olivas said. "We are here to pray we are going to find her."

A search of 12 square miles surrounding the foster home found no trace of the girl. Police have said it's unlikely Everlyse could have gotten far without help from someone.

Investigators have been unable to confirm whether anyone outside of the foster family had seen Everlyse since May 15, Bedwell said.

Everlyse was reportedly wearing a pink T-shirt, pink shorts and no shoes when she was last seen Saturday, the foster family told police. The foster mother told police she discovered the dark-haired, brown-eyed girl was missing about 8 a.m. They contacted police four hours later.

The Carrascals live at 6513 Diamond Point Court with their two children, Melvin Balane, 34, who owns the home, and a 14-year-old boy.

Following Everlyse's disappearance, child welfare officials removed Everlyse's 11-month-old brother, who had also been living at the foster home.
