'He believed she was texting another man' | Argument leads to deadly domestic stabbing inside Maryland laundromat

Coworkers say she died in a pool of blood. Her boyfriend was rushed to the hospital where he remains.

MORNINGSIDE, Md. — More information has become available regarding a woman who was allegedly stabbed to death by her boyfriend while working at Tropoix Laundromat in Morningside on Tuesday. 

A coworker and friend of Yesenia Jaramillo Sosa, 39, who wants to remain anonymous, tells WUSA9, Sosa had just arrived from Colombia less than a year ago. She had been working at the laundromat for about four months.

He said Sosa was helping a client when she was followed to the office and stabbed

“He stabbed her several times and then he stabbed himself in the chest and neck,” the coworker said. 

On Tuesday evening, police said Sosa’s boyfriend, John Marin Morales, 42, stabbed her before turning the knife on himself. 

Her coworkers said Sosa died in a pool of blood, her boyfriend was rushed to the hospital.

The day before the attack, Sosa told her coworker about an argument she had with Morales.

“He believed she was texting another man," the coworker told WUSA9. 

The stabbing marks the 7th domestic related homicide out of a total of 14 homicides so far this year.

Just last week, Prince George’s County officials sounded the alarm on the growing number of domestic cases, after a murder-suicide involving an 11-year-old child.

“You heard these numbers. Last year, there were 25 cases associated with family members using a weapon of some sort to kill a family member,” Police Chief, Malik Aziz, said. 

Morales is still in the hospital in critical condition. He is being charged with first-degree murder.

Detectives are still working to determine a motive.

Sosa leaves behind two adult children who are back in Colombia
