A Maryland man tragically lost his life following an assault while on duty with the state’s transportation department, with authorities pointing to a mother and her teenage daughter as the suspects.

Gregory Turnipseed, aged 71, passed away on the eve of Thanksgiving. In an official statement from Mayor Brandon M. Scott and other city leaders, it was revealed that Turnipseed “sustained severe injuries due to a violent assault.”

The incident reportedly took place on October 20, as covered by Baltimore’s NBC station, WBAL. According to court documents, Turnipseed, a dedicated employee with 14 years at the Department of Transportation, attempted to mediate a conflict over a parking spot. Observing a vehicle waiting for a black Chevrolet SUV to vacate a parking space, Turnipseed approached to inform them of another waiting driver.

This intervention purportedly led to the attack, as detailed by WBAL.

A teenage girl, approximately 15 years old, allegedly exited the SUV’s passenger seat and began striking Turnipseed in the head. The SUV’s driver is also said to have joined in the assault.

“The driver then kicked him in the head multiple times, breaking his glasses, and resulting in abrasions and swelling to his head/face area,” police wrote, according to The Baltimore Banner.

The alleged driver has since been identified as 49-year-old Kiannah Bonaparte — and investigators say she is the teen’s mother.

Turnipseed did receive medical attention that day, but was admitted to the hospital three days later after suffering a brain bleed, WBAL reported. His condition worsened during recovery, and he died on Wednesday.

But before he passed away, Turnipseed was reportedly able to identify his alleged attackers. According to local Fox affiliate WBFF, investigators on Nov. 6 showed Turnipseed a photo array of potential suspects — and he identified Bonaparte as one of his two attackers.

Court records show Bonaparte has been charged with assault. It was not immediately clear whether those charges would be upgraded following Turnipseed’s death.

Records show that Bonaparte is scheduled for a preliminary hearing on Dec. 11. Police have not indicated whether the teen has been arrested.

Turnipseed’s family members have been outspoken in their grief — and their frustration.

“I’ve been robbed of my father,” Lacheryl Turnipseed-White told WBFF, adding that the suspects “could have just drove off and went their way … and let him go his way.”

The teen, Turnipseed-White said, “even wanted to assault an elder or someone that wasn’t even doing anything to her. Just minding his own business basically. All he was truly doing was his job.”

City officials praised Turnipseed for his dedication and contribution to Baltimore.

“Mr. Turnipseed was an exemplary public servant, a 14-year veteran of BCDOT working in the Traffic Division,” the joint statement from the mayor’s office said. “He served Baltimore with dignity and integrity, and we will forever be grateful for his dedication to our city. We will continue wrapping our arms around his family and loved ones, holding them close in our hearts and prayers.”
