Denver District Attorney Beth McCann dropped one of two murder charges against the man who allegedly shot and killed two brothers on I-25 in June.

Stephan Long, 25, appeared in court on Wednesday for a preliminary hearing on two first-degree murder charges stemming from an incident that occurred on June 13. During the hearing, Denver prosecutors dropped one of the two murder charges, according to the Denver District Attorney’s Office. They will continue to pursue one of the murder charges, though, after the judge ruled Wednesday there’s enough evidence to take the case to trial.

“After reviewing all the facts involved in the death of Blake Lucas, we did not believe that we could prove Mr. Long’s guilt beyond a reasonable doubt,” Matt Jablow, a spokesman for Denver District Attorney Beth McCann, told The Denver Gazette.

The shootings occurred around 3 p.m. on June 13 on I-25 between West 6th Avenue and West 8th Avenue. Two cars had stopped and two passengers got out of one vehicle and approached the other. The brothers — later identified as Blake Lucas, 21, and Damon Lucas, 22 — walked up to Long’s car, according to the Denver Police Department.

Long allegedly shot Damon Lucas. Long began to drive off, but Blake Lucas grabbed on to the vehicle. Long allegedly fired several shots as he drove off the highway at West 8th Avenue, hitting Blake and causing him to fall off the car, according to police.

Long did not call the police and fled the scene. Both victims died from their injuries.

Long said the victims had instigated the incident and yelled at his vehicle, according to his reported statement. He said the men approached his car, grabbed him and hit him.

Eleven Denver City Council members sent a letter to McCann on Oct. 9 expressing concern about the way the office was handling the case, questioning a potential “double standard.”

The city council members pointed toward the case regarding Elias Armstrong, a 12-year-old Black child who was shot and killed by 35-year-old White man, Jack Reed. Reed — who tracked his car with a GPS device after it was allegedly stolen by Armstrong and other teenagers — claimed self-defense and was not criminally charged by McCann.

“Both claimed self-defense. Both appear to have had legal and registered firearms and claimed self-defense fearing their life was in danger in their use of their firearm. Yet they have been treated in drastically different ways,” the letter from city council said of Reed and Long’s cases.

The letter authors insinuated the charging decisions were racially motivated since Long is Black.

After the initial charges against Long in August, McCann said: “My office evaluates each case strictly on its merits and based on whether we believe we can prove a defendant’s guilt beyond a reasonable doubt. That is exactly what we did in this case.”
