Not from the Lakewood Police Department's perspective.
According to the LPD, the parent in question, who's not yet been identified, claims to have "inadvertently" left the weapon in the backpack of the Molholm Elementary student. And for that mistake, he could face multiple charges, including child abuse.
Next time, don't keep the gun on the same shelf with the peanut butter. Here's more detail from an LPD release:
The Lakewood Police Department received a call [Wednesday] afternoon from Molholm Elementary School located at 6000 West 9th Avenue in reference to a found hand gun.
A teacher was cleaning up and discovered the weapon in a backpack belonging to a kindergarten student. The hand gun belonged to a parent of the student [who] inadvertently left it in the child's backpack prior to taking the child to school in the morning. The gun was secured by school personnel until Police Agents arrived on scene. The parent was taken into custody without incident. Charges pending include child abuse and possession of a weapon on school grounds.
The identity of the parent is not being released at this time.
