Rising ESPN reporter Edward Aschoff unexpectedly died on Christmas Eve which also happened to be his 34th birthday.

“We are very sorry to have to share the devastating news of the tragic passing of friend and ESPN colleague Edward Aschoff,” ESPN shared in a statement on Tuesday. “He died earlier today, his 34th birthday. Our thoughts are with his loved ones, including his fiancée, Katy.”

Aschoff’s exact cause of death was not released, but the young reporter had been suffering from pneumonia in both lungs since early December. He even took to Twitter to ask his followers for advice on the illness.

Young adults are typically at a lower risk of contracting pneumonia. However, CBS reports that half of adults with normal immune systems who are hospitalized with severe pneumonia are younger adults.

The CDC states the lung infection kills about 50,000 Americans every year.

The 34-year-old leaves behind his fiancée, Katy Berteau. The two became engaged last year after Berteau proposed with a Godzilla-shaped ring, Aschoff’s favorite film character. They were set to marry in April.

In his last Instagram post, Aschoff thanked his fiancée for support during his illness.

“Having pneumonia is pretty terrible…But it helps having this sweet angel taking care of you even when she’s risking getting this soul-crushing illness herself,” he wrote on December 4th. “Thanks for putting up with my 5 am coughing fits.”

Aschoff joined ESPN in 2011 and quickly proved to be a great addition to the network. He was often on the sidelines reporting on college football games across the country and reported for various ESPN platforms, including SportsCenter.

In 2016, he won first place in the Football Writers Association of America’s contest in enterprise reporting for his reporting on race and discrimination in college football. He shared the honor with fellow ESPN reporter Adam Rittenberg.

Several of Aschoff’s ESPN colleagues paid tribute to him on-air and on social media after learning of his untimely passing.
