A 5-year-old boy in Denton, Texas was reportedly in critical condition on Saturday after an accidental shooting involving an 8-year-old friend.

KXAS-TV reported that the two boys were alone in a bedroom when the 8-year-old found a .22-caliber rifle and pointed it at the younger boy. Police said the older boy then accidentally shot his friend in the left side of his head. Two adults, including the 5-year-old boy's grandfather, and a teenager were also inside the home at the time of the shooting.

The younger boy was first taken to a local medical facility, then transported by air to Children's Medical Center in Dallas, Texas. KTVT-TV reported that he was on a ventilator as of Saturday evening.

"It's a very tragic accident, especially the day before Mother's Day," said Denton Police spokesperson Orlando Hinojosa. "Education is the most important thing about firearm safety. Just make sure your children know, if you do have weapons in the house, where they're at, and for them not to be reachable."

This incident is the third shooting involving children in Texas this week, and the second involving a .22-caliber rifle. On Tuesday, Houston officials said a 5-year-old boy was handling one when he accidentally shot his 7-year-old brother while the two were taking a bath. And on Wednesday, a 2-year-old boy in Corsicana shot himself in the head with his father's handgun.
