Updated at 12:14 p.m. Wednesday to reflect that the boy died.

A 14-year-old boy died the day after his twin brother accidentally shot him in the head while trying to kill a snake in southeast Texas, authorities said.

The shooting occurred just before 4 p.m. Monday on County Road 2342 in Liberty County, about 50 miles northeast of Houston, KHOU reports.

The victim died Tuesday night in Houston, where he'd been flown for treatment, the Liberty County Sheriff's Office said.

The investigation is ongoing, but at this time the sheriff's office said it does not anticipate any charges will be filed in the "tragic accidental shooting."

The boys reportedly got two .22-caliber rifles from their house after they saw the snake in a drainage ditch.

As one of them aimed and fired at the snake, the other knelt down suddenly and was struck above the right ear, the Liberty County Sheriff's Office told ABC13.

Capt. Ken DeFoor said the shooting is a lesson for families, the station reports.

"These guns that are left unsupervised in the home," DeFoor said. "There should definitely be training on how do you properly use these weapons. These boys were 14 years old. They were certainly old enough to be taught the proper handling of firearms, what they should and should not do."

"Never ever put yourself in the front of one like was done today. It was a thoughtless act that resulted in a tragic accident."

The siblings aren't expected to be identified because they're minors.
