Police believe six first responders were in the home when Washington, a mother of five, was killed. They were helping her boyfriend, who was apparently having a heart attack, officials said.

"That’s kind of cowardly to me. I know they are not the police, but what does it take for you to step up and help. What does it take? You watched her get murdered. You watched that," said Leslie Washington, Romaira Washington's mother.

Detroit Fire Commissioner Eric Jones said he couldn't comment because the investigation is ongoing.

Detroit Police Chief James Craig said the department is investigating.

"We are now learning some disturbing details," Craig said. "We have opened an investigation."
