Tom Bearson was just 18 years old when his body was found in an RV lot in Moorhead in 2014.

Bearson would have turned 21 earlier this month and it is still not known who his killer is.

The Duluth News Tribune recently published an article talking to Bearson's parents where the pain has not gone away.

Police said Bearson's death was due to "homicidal violence" but no other information has been made public. At the time, Bearson's friends who he was with at the time had not agreed to take a polygraph test. Polygraph test results are not admissible in court anyway according to the Duluth News Tribune.

A golf outing has been held in Bearson's honor every year since his death, the third of which occurred on July 15.

Just yesterday a Reddit user posted to the social networking site trying to figure out how three years later there are still no answers.

According to an article from 2015 in the Grand Forks Herald, nobody is working full-time on the investigation but investigators do come back to it from time to time.

This September will mark the three year anniversary since Bearson originally went missing but unfortunately it does not appear as though investigators are any closer to finding any answers.
