Amy Blanc Lacy, 62, a script supervisor known for her work on the television series The Walking Dead and Halt and Catch Fire, died after a hit-and-run collision in Atlanta on Sept. 1, police said.

Lacy was riding in the back seat of a car driven by her son, Oliver Lacy, 23, when a vehicle driven by Buck Rollins, 31, struck their vehicle after reportedly driving over the curb and launching into the air. The Atlanta Police Department said Rollins was traveling 91 mph in a 45 mph zone at the time of the crash. Lacy was critically injured, taken to a hospital and died after spending four days in a coma. Oliver Lacy and another son, Adrian Lacy, 25, were also hospitalized.

Police said Rollins fled the scene after the collision and was later seen on video retrieving golf clubs from his vehicle and walking away. An arrest affidavit obtained by People and cited by police indicates investigators recovered data from the airbag control modules showing Rollins removed his foot from the accelerator and began braking 2.5 seconds before impact, a detail the affidavit said calls into question Rollins’ later claim that he had a seizure during the incident.

Rollins turned himself in to authorities and was charged with first-degree homicide by vehicle, hit and run, reckless driving and speeding, Atlanta police said. Jail records show he was released on a $70,000 bond.

A witness, Stacey Elgin, told local station Fox 5 she tried to stop the fleeing driver after making a U-turn and following the vehicle. "I did follow the car because this person obviously caused a terrible wreck because I knew we had the green light, and they're trying to get out of the situation," Elgin said.

Colleagues in the film and television community paid tribute to Lacy following news of her death. Actor Khary Payton, who played King Ezekiel on The Walking Dead, wrote on social media that Lacy had been "an angel" and that he would be "looking for you in all the little beautiful things." Director Erin Lee Carr described Lacy as a "bright light" on set who brought a "meticulous eye and fierce heart to projects."

A GoFundMe page established to assist with funeral expenses and support Lacy’s family describes her as "a radiant and beautiful presence in the Film Community," and notes she raised three children.

Lacy’s credits listed on industry databases include work as a script supervisor on episodes of The Walking Dead and the series Halt and Catch Fire. Script supervisors are responsible for maintaining continuity and detailed records during production, a role collaborators and directors often cite as essential to a show's day-to-day execution.

The case remains under investigation by Atlanta police. Court records and the arrest affidavit provide the basis for the charges; prosecutors will determine whether additional charges are warranted as the investigation continues.
