Flores allegedly told investigators he shot Doolittle twice in the head, then drove her body across the state because “he (was) upset with her.”

Investigators said she ended her relationship with Flores just a few weeks before her death.

Flores was reportedly “distraught” because of the recent breakup with Doolittle.

Doolittle was the Boulder County Fair lady-in-waiting when she was killed and was crowned queen posthumously in July.

Flores will enter a plea an arraignment Thursday afternoon, the Boulder Daily Camera reported.
