The Johnson County Attorney’s Office on Wednesday changed 50-year-old Miranda Lalla’s charges from second-offense OWI to a Class-B felony vehicular homicide.

Lalla was charged on June 18 with second-offense OWI after allegedly running over 44-year-old Pamela Gross with a truck. Lalla was being held at the Johnson County Jail on a $50,000 cash bond as of Wednesday evening.

Police officials responded to 315 E. First St. June 18 after receiving a report of a motor-vehicle accident with an injury. According to a police complaint, Lalla got into her truck — after driving Gross home and allegedly physically fighting with her — and while attempting to leave, knocked Gross over with an open door and ran her over, resulting in her death.

Lalla told police officials she had a few beers that evening, and when she agreed to field sobriety tests, it resulted in a reading of .093, according to a law-enforcement report.

She was previously convicted of OWI in May 2006.
