Streamwood police said Jalonie Jenkins, 25, was taken into custody in Downers Grove Sunday night without incident.

Police were sent to the 1600-block of McKool Avenue at about 7:50 p.m. Wednesday and found the two victims dead from the stabbing.

The Cook County Medical Examiner’s Office has confirmed the identities of the victims as Eyani Jones, age 10, and Janiya Jenkins, age 21. ABC7 discovered that the victims were siblings.

Friends of the victims told ABC7 Jalonie Jenkins is the older brother of the two victims.

A nearby neighbor and family friend in Streamwood said she ran over to check what happened when the victim’s 7-year-old brother asked for help.

“I called the police and they’re asking me questions like, what’s the address, what happened?” she said.

An unidentified woman revealed that her daughter was speaking with her best friend, Eyani, just before 8 p.m. on Wednesday, when a loud disturbance was heard in the background.

“She heard the screaming,” the woman recounted. “They were talking on the phone, and my daughter said, ‘I don’t know what’s happening at Eyani’s house, but could you take a look out the window?'”

Minutes later, Eyani’s younger brother came to the neighbor’s door asking that she call his mother, who was at work.

She did after walking over to see for herself the terror that unfolded.

“I walked up the stairs and I saw blood and stuff everywhere,” she said. “I see the oldest girl laid there, I see the little girl she’s laid out. I’m on the phone with the mom. I’m telling her, ‘Oh my God your kids are gone.'”

This woman’s daughter was the last to talk to the 10-year-old who just began summer break last Thursday.

“I ain’t never witnessed nothing like this,” she said. “At the end of the day, this little girl has spent nights at my house. We even went to hotels together. This is my daughter’s best friend.”

“It’s just heartbreaking and it hurts real bad,” the woman said. “It hurts so bad so bad.”

Jasmine Marshall said she was close with 21-year-old victim Janiya Jenkins. She came to the house in Streamwood Thursday afternoon hoping to get more information.

“I’m hurt. I’m really hurt,” Marshall said. “She was a really good friend. A good friend.”
