A Chick-fil-A drive-thru in Rome abruptly turned into a crime scene Wednesday morning when a man walked up to a woman’s car, fatally shot her and then shot himself as commuters waited in line for breakfast.

Rome police were called to the fast-food restaurant on Shorter Avenue around 7 a.m. for what was initially reported as a vehicle crash with injuries, the department said in a statement. They were then notified it had actually been a shooting.

The preliminary investigation indicates that Cassie Davis, who had just turned 39 on Friday, was waiting in the drive-thru when 56-year-old Anthony Green pulled into the parking lot, got out of his vehicle and shot her three times through the passenger-side window, according to Floyd County Deputy Coroner Chris Giles. Green then turned the gun on himself, delivering one fatal shot, Giles said.

As Davis’ foot came off the brake, her vehicle then rolled forward and hit a power box before going down an embankment into traffic, which is why the incident was initially reported as a wreck, Giles said. No other vehicles were involved.

Police have not released details about what may have sparked the shooting, but Giles confirmed the two had previously been in an apparent relationship.

The restaurant was closed for the day. The general manager released a statement Wednesday afternoon.

“Rome Community, a horrific incident occurred outside our restaurant this morning,” Greg Major said. “We are currently cooperating with the police who are investigating. No other guests or team members were hurt but we mourn with the community. We have closed the restaurant for the day to repair and care for team members. Thank you for your patience during this time; we plan to reopen (Thursday).”
