A 21-year-old college student who was studying to become a police officer has become the youngest person in Colorado to die of coronavirus, reports said.

Cody Lyster, who played club baseball at Colorado Mesa University, died Tuesday when his heart stopped as doctors tried to put him on dialysis, the Denver Sentinel reported.

Lyster had been in the hospital for about a week fighting the virus until he died, according to the report.

In a Facebook post, his father Kevin Lyster, mourned his son’s death — and warned others to take the virus seriously.

“How do I craft the words to say I love you,” he wrote in the post.

“The doctors worked on our son for half an hour and at 11:55 p.m. our beloved son and my best friend, Sierra’s brother and Lea Ann’s baby boy left this world to play baseball on the field of dreams,” he added.

“We were able to say goodbye to him, hug him and hold him afterwards. Please take this virus seriously. We are hollow and at a loss for words,” Kevin Lyster wrote.

Cody had been majoring in criminal justice and hoped to become a police officer after graduation, according to the report.
