A Galveston County middle school student who collapsed during a basketball game Monday night died because of a heart abnormality.

She was the second young player to die in less than a week, and in both cases, the girls each had a congenital cardiac abnormality.

On Tuesday, Kailynn Boclair’s teammates honored her with ribbons, the school had the flag at half-staff and the Hitchcock community was in tears.

“Everybody in the school, they're really crying right now and I'm just trying to keep strong,” said Boclair’s Crosby Middle School classmate Derrell Harrison.

So was Crosby Middle School's 7th grade basketball coach for the girls.

Unable to talk on camera, she walked over to the sidelines and broke down. It was where she had stood last night during a game when she saw Boclair go down on the court within the last minute of the game.

Her uncle got the call from Kailynn's grandmother.

“What's wrong with Kailynn? She's just lying on the court, she's not moving, she's not breathing, she's just lying there,” Harold Evans recalled from the phone conversation.

The boy's basketball team was coming back from a road game when they heard the news.

“My friend named Melissa, she said pray (for) Kailynn. She's passed out and her eyes have rolled to the back of her head,” student Chris Scott said.

The Galveston County Medical Examiner says Kailynn had an abnormal blood vessel in her heart, a condition that can go undetected and cause sudden death.

The same condition claimed the life of 13-year-old Jocelyn Arias. She collapsed at a Sugar Land middle school basketball practice last week.

At Crosby Middle School in Hitchcock, it was a day -- especially for the athletes -- to come to terms with a different kind of loss.

 “If it was her time to go, it was time to go. (You) can't be mad at that,” said Scott.

The irony in all of this was that Kailynn was having one of her best games when she collapsed. It’s a practice her uncle believes she'll continue.

“I know she’s in a better place and she's playing basketball for a better, for a good team,” said Evans.
