A mother whose 2-year-old was accidentally shot with a handgun gave the boy Tylenol (search) and put him down for a nap, waiting more than four hours to go to a hospital, police said.

Sylvia Ann Alcozer (search), 21, turned herself in Thursday on charges of felony child endangerment. She was scheduled to be arraigned Friday.

Nathan Vela, 2, was shot Nov. 11 by his 17-year-old uncle. He was hospitalized after the bullet hit his arm and went into his chest then stopped near his spinal cord. He had broken ribs and a punctured lung, according to the complaint. He's now in the custody of relatives.

The boy's uncle, Marcus Cruz Alcozer, remained in the Potter County (search) Detention Center on Friday on bail of $7,500. He has been charged with reckless injury to a child causing serious bodily injury, a second-degree felony.

According to a criminal complaint, Alcozer told police the gun discharged accidentally. He dropped it, picked it up and pulled the trigger without checking to see whether it was loaded, the complaint states.

The mother "told police that she only thought the bullet had grazed her son's arm and it only bled slightly," the complaint states. "Officers retrieved a sock and a cloth which had been used in an attempt to stop the bleeding."

The mother took Nathan to a hospital about 4½ hours after the shooting, according to police.

Child Protective Services placed the boy with relatives late this week, said Holly Campidilli, a spokeswoman for the Department of Family and Protective Services.

"From what we were told, he's doing well," she said Friday.

Roberto Guadalupe Vasquez, 19, has been accused of unlawfully transferring a handgun to a child younger than 18. According to police complaints, Alcozer was buying the .22-caliber semi-automatic handgun from Vasquez.
