Trying to understand such a tragedy can be difficult - especially for a 7-year-old child. But a young boy in Littleton, whose own father is a Parker Police officer, asked questions, heard the difficult answers, and after processing it all, decided he needed to do something to help.

7-year-old Mason Nelsen stood out in the cold Monday, for about two hours, in his neighborhood selling hot chocolate, cinnamon rolls, and art work to help raise money for Deputy Parrish's family.

He drew the pictures specifically for Monday's sale.

His artwork represents love for our men and women in blue and he drew it specifically for the fundraiser to help the Parrish family.

Jefferson County Sheriff's Deputies were some of the customers who stopped by his stand.

Mason's mother, Jessica, says he raised $470 at his sale, but family friends who missed the sale are mailing them donations.
