May 2—Two more parents indicted by a grand jury for allowing minors to drink following an investigation into Boulder High prom parties the night of a fatal DUI crash in Boulder have taken plea agreements.

Mark and Pam Sunderland both pleaded guilty Monday to a misdemeanor count of allowing alcohol to be provided to a minor, according to the Boulder County District Attorney's Office.

They received deferred judgments and were each sentenced to 12 months of probation, with conditions including 75 hours of community service focused on preventing drinking and driving, a Mothers Against Drunk Driving victim impact panel and a $750 fine.

Five parents, two companies and a Boulder liquor store were all indicted by a grand jury following an investigation into a culture of underage drinking sparked by a fatal crash in 2022 in which a juvenile driver killed Ori Tsioni, 33, and Morales Ramirez, 49, and seriously injured Diana Spencer while driving the wrong way down Foothills Parkway.

The driver, Natalie Hill, pleaded guilty to charges including vehicular homicide and vehicular assault and was sentenced to nine months of work release and three years of probation.

A grand jury investigation into the night of the crash resulted in indictments for five parents: the Sunderlands, Elise Miller and Todd and Charlene Hoffman.

According to the indictment and a pending batch of civil suits, Hill was drinking along with several other Boulder High students at a party hosted by Miller, who is alleged to have provided alcohol to underage drinkers.

The students, including Hill, then got onto a party bus from Sunset Luxury Limousines where they continued to drink.

The initial indictment alleged that following the prom, Hill and the students went to the Sunderland's residence where they continued to drink, but prosecutors said it was determined Hill did not consume alcohol at the Sunderland's residence.

But Boulder County District Attorney Michael Dougherty said other minors were allowed to drink at their residence.

"This couple allowed minors in their home to consume alcohol despite being underage," Dougherty said in a statement. "The juvenile driver responsible for the fatal crash did not, in fact, drink at their house. Nonetheless, the investigation revealed that other minors did so.

"The culture fostered by these adults and others violated the law and must stop. The loss of life alone should send that message to parents. And, between the criminal charges and the civil suits, it should be clear that this conduct is dangerous and unacceptable."

The Sunderlands released a statement Monday.

"We are pleased that the District Attorney's office has reviewed all the facts in this case and has determined that we were not involved in the tragic events of that night," the statement read. "However, we are very disappointed in how this newspaper (the Daily Camera) has repeatedly portrayed us as responsible for the actions of Natalie Hill that evening, without attempting to understand the facts that have long been known. We look forward to helping facilitate conversations around the culture of underage drinking that exists in our community."

Miller and the Hoffmans already reached plea agreements in their cases.

The civil suits, which names the Sunderlands, remain pending.

Two businesses and the driver of the party bus were also indicted, and those cases are also pending.
