The Daytona Beach, FL, police officer who was shot in the head June 23 remains in critical condition, according to an update from his family the police department shared online.

The police department tweeted the update Wednesday, saying Officer Jason Raynor, who authorities say was shot in the head last month by Othal Wallace, has shown some signs of improvement since the shooting but has also had some setbacks, ClickOrlando reports.

“Jason remains in critical condition, there have been some signs of improvements, there have also been some setbacks that prevent us from delivering all good news,” department officials wrote in the tweet. “He has a long road ahead, but we remain positive.”

This week's update was one of very few updates shared by officials on Raynor’s condition since the shooting, which took place while Raynor was checking a suspicious vehicle.

Raynor has been listed in critical condition since the shooting.
