DODGE CITY, Kan. (AP) - A Dodge City man pleaded not guilty to unintentionally killing a high school student earlier this year.

Fabian Colorado entered the plea Friday to involuntary manslaughter and battery in the May 14 death of Diego Enriquez-Enriquez.

The teenager died after suffering a head injury during a party.

The Dodge City Daily Globe reports that several witnesses at Colorado's preliminary hearing said they either saw him punch
Enriquez-Enriquez or heard the victim hit his head on a concrete floor.

Defense attorney Derek Miller said that Colorado's defense will conduct its own investigation because the witnesses gave different
versions of what happened.

A pretrial hearing and a trial date have not been set.
