Cahokia, IL (KSDK) - A Cahokia teenager shot in the head is in critical condition. Her friend who was also shot has been released from the hospital.

Meanwhile, another teenager is in jail charged in one of the shootings.

Amos Bullocks, 18, has no criminal record police know of, but is now facing an attempted murder charge.

Investigators say he shot a 16-year-old girl. After that police and neighbors say she ran for help along Falling Springs Road.

"And she knocked on everybody's door she could until somebody opened up the door and let her in," said Corlis Haywood, who lives on Falling Springs Road. "She was screaming, he's trying to kill me, he's trying to kill me," Haywood says she heard from a neighbor.

She added, "They thought her throat was cut but we found out that she had got grazed in the neck with a bullet."

She was shot in the backside as well and told police Bullocks pulled the trigger. After his arrest, and hours later at the hospital, the 16-year-old told police there may be another victim, a 17-year-old friend who was with her.

Right around that time, a call came in from a guy walking to bus stop. He heard a cry for help and he turned and saw the girl lying in a wooded area somewhere. She had been shot twice in the head.

Charles Collins, who also lives on the street said, "What would another person do, you know, teenagers like that, where you have to retaliate by shooting them in the head?"

Police are still working on the motive. Despite the head wounds, the girl was talking and moving, but she's in critical condition. Because the investigation is not over, charges have not been filed, but police do believe Bullocks did it.

"These young kids, man, they need to find something positive to do with their lives man, you shoot somebody, man, your life is over," said Collins.

Bullocks is in the St. Clair County Jail on a $1 million bond.
