Police say Johnny Mize II shot Jake after he and his cousin Jack Ulrich stole $600 worth of fireworks from the stand Mize's dad owns.

The assistant district attorney says Jack Ulrich admits to stealing the fireworks, but that only counts for a misdemeanor.
We also learned Jake Ulrich's mom, Jacklyn, is in the Washington County jail facing a failure to appear charge not related to the shooting death of her son.

Ramona Police say Jacklyn was involved in the kidnapping and torture of two men during an attempted drug deal in Washington County in 2014.

Following the arraignment, Nathan Milner, the attorney for Jake Ulrich and several members of the family released a statement. You can read the full statement below.
