Prosecutors could determine whether to file charges against the driver involved in a fatal hit-and-run accident by the end of the week, Douglas County District Attorney Charles Branson said Tuesday.

“We’re in the process of reviewing all the materials,” he said.

The police said 21-year-old Joel Hernandez had been drinking before he hit 20-year-old Rachel Leek, who was riding her bicycle in the street. The accident occurred about 2:20 a.m. Oct. 16, just south of 10th and Tennessee streets. Leek died the same day from her injuries.

Police officers made no arrests in the hit-and-run accident — a decision Branson said gives his office more time to determine what charges to file in the case, if any. With an arrest, prosecutors must make that decision almost immediately.

“They thought it was more beneficial to continue to gather information and continue their investigation, as opposed to (forcing) the investigation by making an arrest,” Branson said.
