BALTIMORE, Maryland — A Baltimore man has been charged with first-degree murder in the fatal stabbing of his wife, a MedStar Good Samaritan Hospital employee who was attacked in the hospital's parking lot on Friday morning, according to Baltimore police and court charging documents reported on Monday night, November 9. Tiera Gamble, 36, died of her wounds at the hospital where she worked.

Police said officers were called to MedStar Good Samaritan Hospital at around 8 a.m. on Friday for a report of a stabbing, and found medical professionals attempting — unsuccessfully — to resuscitate Gamble. She was the executive assistant to the director of psychological services at the hospital, according to the charging documents.

According to the charging documents, a witness saw Gamble fall out of the front driver's seat of a car in the hospital's lower parking lot. A man identified by police as her husband, 37-year-old Marquis Johnson, was then seen getting out of the vehicle's passenger seat, switching to the driver's seat and driving off. "Gamble was then observed running several feet before collapsing, where she was observed to be suffering from apparent lacerations," the charging documents state.

Who Tiera Gamble was

Gamble, 36, worked steps from where she was attacked: she was the executive assistant to the director of psychological services at MedStar Good Samaritan Hospital, a hospital in northeast Baltimore, according to the police charging documents. The attack happened as she arrived at her own workplace on a Friday morning, in a parking lot at the start of the working day.

Colleagues inside the building became her rescuers: when officers arrived at around 8 a.m., medical professionals were already attempting to resuscitate her, police said. She could not be saved.

How police say they built the case

After reviewing surveillance footage taken at the parking garage, police obtained a search warrant for a residence believed to have been shared by Gamble and Johnson, according to the court documents. Johnson was taken into custody at that home, police said.

Investigators said they recovered a kitchen knife set that matched the description of the large kitchen knife found near Gamble's body. The charging documents also state: "At the time of his arrest, Mr. Johnson was wearing distinctive blue tennis shoes that appeared to match the shoes worn by the suspect observed in surveillance footage recovered during the investigation of Ms. Gamble's murder."

Johnson has been charged with first-degree murder, first-degree assault and related charges in connection with Gamble's death, according to the court documents. These are charges, not a conviction: he has not been tried, and the account above is the police and prosecution version set out in charging documents, which he is entitled to contest in court.

What happens next

Homicide detectives are continuing to investigate the incident, Baltimore police said, and the case will now move through Maryland's courts, where Johnson will face the first-degree murder and assault charges. No court date was given in Monday's reporting.

For hospital staff and patients, the case has turned a workplace parking lot into a crime scene and raised the question every hospital worker in the city will recognise: the walk from the car to the ward at the start of a shift is part of the working day, and on Friday morning, at one of Baltimore's hospitals, it was where a 36-year-old employee's life ended.
