She told Eyewitness News on Tuesday that Sam remains in ICU at Memorial Hermann but is "doing OK." She said he's being monitored closely by doctors and nurses.
Public information officer for the Fort Bend County Sheriff's Office Jessica Reyes told ABC13 the crash was reported as a one-car rollover at the Katy-Flewellen Road and Spring Green roundabout.
She said Sam's car rolled over at least twice.
"According to preliminary investigation, speed is believed to be a factor," said Reyes.
Eyewitness News is also awaiting a response from Katy ISD.
Meanwhile, a prayer event organized by friends and loved ones was held Sunday night to honor the young athlete.
"Sam is one of those gritty guys ... he's the kid that's going to run the quarter and run his guts out," said Todd McVey, the head coach of the Tompkins H.S. football team. "Right now, it's just taking it one day at a time, and keep the prayers coming from everybody in the community. He's fought through some things and continues to fight."
A GoFundMe page has also been created to help the teen's family.
