Blake Garrett, the former child star who appeared in How To Eat Fried Worms, has died at 33.

Garrett’s mother Carol announced that he had died on Sunday, according to TMZ.

She told the publication that her family was still in the dark about what had caused her son’s death.

Garrett’s body was autopsied, but his family won’t know the cause of his death until the medical examiner’s report is released.

Garrett — who was born in Austin, Texas — was best known for starring in the 2006 theatrical adaptation of the classic children’s book, How To Eat Fried Worms. 

His mother described his final days in Tulsa, Oklahoma, as being consumed by painful medical issues.

According to TMZ, Carol said her son made a trip to an Oklahoma emergency room last week after he was stricken by excruciating pain.

The condition was allegedly later diagnosed as shingles, an extremely painful rash that can occur when the chickenpox is reactivated years later in people who contracted it when they were younger.

Although the condition is more likely to affect older individuals, around one in three people will develop shingles in their lifetime, according to the CDC, though that number may decrease over time thanks to the increasing prevalence of childhood vaccinations against chickenpox. 

Carol said she feared that the pain from the shingles might have led her son to use other substances to self-medicate. 

She reportedly worried that Garrett could have died as the result of a tragic accident as he tried to cope with the illness. 

It’s unclear what substances she feared her son may have been using, but the former child star had allegedly been sober in the past three years. 

Garrett got an early start in show business as a child, when he reportedly engaged in local theater and acted in productions of Aladdin and His Magical Lamp and Peanuts: A Charlie Brown Tribute.
