Landon Clifford, a YouTube celebrity, died on August 19, according to his wife Camryn Clifford and a GoFundMe page. He was 19.

Clifford, whose YouTube channel – Cam&Fam – explored his life as a teenage father and husband, had a brain injury and went into a coma for six days beginning August 13, Camryn said.

His wife wrote on Instagram, “He was an amazing husband and the best father those girls could (have) ever asked for. It saddens me deeply that they will never get to truly know him.”

“He was so young and had so much more life to live,” Camryn added. “This isn’t how things were supposed to go.”

Camryn did not reveal the cause of his death.

Landon’s YouTube channel Cam&Fam had 1.3 million subscribers, according to CNN.

The videos they posted documented their lives as teen parents to their daughters, Collette Briar Clifford, 2, and Delilah Rose Clifford, who was born in May. They married in June 2019.

Debuted in 2018, the channel featured video blogs and Q&A sessions.

They posted their latest video a couple of months ago, according to CNN. Landon and Camryn posted their first clip on YouTube after Camryn gave birth to their first daughter when she was 16, according to PEOPLE.
