Three people killed in apparent double murder-suicide were all nurse anesthetists working at Baltimore-area hospitals

Three people were killed in an apparent double murder-suicide Saturday that spanned from Baltimore City to Howard County.

Police said Rajaee Shareef Black shot and killed his ex-girlfriend, Tara Labang, inside a home in South Baltimore. Police said he traveled to Columbia and shot his ex- wife.

In between the killings, Rajaee stood outside his former wife's apartment building and said in a Facebook Live video that he "just did something crazy." He said that he shot Labang in the head and that it felt like a dream. He said he was going to kill his wife and himself.

Labang worked at the hospital as a certified registered nurse anesthetist, helping administer the proper doses of anesthesia for surgeries and other procedures.

Bradley Cardwell wrote in a statement that the hospital was shocked and sad by the news. Tara will be missed by all of Ascension Saint Agnes.

Cardwell said that the hospital's spiritual care department and employee assistance program are being used to help those in need.

The University of Maryland Capital Region Health is where Labang worked.

Matthews wrote in an email that they were deeply sad about the death of a team member who cared for patients in the hospital. We are offering grief counseling to her colleagues.

Yul McIntyre said he met Labang when she was in training as a nurse.

She was a hard worker. She was fun to be around. McIntyre said that she had a smile and energy that made people happy.

McIntyre said it was great to watch Labang warm up in the operating room. She joked that he shouldn't put her to sleep when McIntyre played music. Hip-hop was a favorite.

McIntyre ran into Labang at MedStar Good Samaritan Hospital, where they both worked, after not seeing her in a few months.

We were coming around the corner and she said, "Yul!" and I said, "Tara!" McIntyre said something. She gave me a hug.

She told him that she was trying to find a permanent job after working at various hospitals. McIntyre said that Labang snapped a selfies with him in the employee lounge.

McIntyre said that the team at Saint Agnes prayed for Labang and the other victims of Saturday's tragedy.

McIntyre said they were all in it for her.

Sharon Sopp said that Wendy Black had worked at Howard County General Hospital for nearly five years.

Rajaee worked as a nurse anesthetist at the U.S. Department of Veterans Affairs.

The department plans to offer grief counseling to his colleagues.

Rajaee Black worked for the University of Maryland Capital Region Health for 3 1/2 years.

The University of Maryland Medical System fired Rajaee Black after he exposed a doctor who was hiding drugs in his locker, according to court records.

The system did not comment on the case due to a policy of not commenting on pending litigation.

The founder and CEO of the Diversity in Nurse Anesthesia Mentorship Program said on Monday that she taught both Blacks and Labang.

She wrote that the news of 3 CRNAs who were killed shattered her heart. They were nurses and I was their mentor. Three souls are gone.

The Southern District station of the Baltimore Police Department received a call about a residential alarm in the 1500 block of Marshall Street.

Howard County Police officers were called to the Kings Contrivance neighborhood in Columbia for a report of shots fired just after noon. Wendy and Rajaee Black were found dead.

Baltimore Police tried to alert Howard County authorities to a video of Black on Facebook Live where he mentioned he was planning to kill his ex-wife but it was too late.

He said in the video that he didn't think he would be that guy. The person that started my depression is my ex-wife. So, she's next. I will do myself as well.

Black said in the video that he was upset about the issues between the two women. Three years have passed since he and Wendy Black began a custody battle. The history of domestic violence charges was not shown in the records.

The Blacks' two young children were in his car when the killings occurred, but were found unharmed.
