A woman from Greenbelt who was described as possibly in danger after being reported missing last week has been found dead with stab wounds to her torso, authorities said.

The body of the woman, Emilia Arabelly Ignacio, 28, was found in a car that was discovered Friday afternoon near Frankfort Drive and Frankfort Court, Greenbelt police said.

The police said they have obtained arrest warrants charging her boyfriend with first- and second-degree­ murder in her death. They identified him as Juan Miguel Roman, 34. He is also known as Juan Miguel Roman Balderas.

The woman was last seen Monday with him, police had said Thursday in a flier asking for help in locating her.

They said she was reported missing by relatives Wednesday evening after they had not heard from her or her boyfriend and were unable to reach her.

In the flier, police said that recently disclosed text messages sent to a relative of the woman indicated that “she may be in danger.”

The flier described her as a “critical missing person” and said she and her boyfriend might be using one of two vehicles. The vehicle in which she was found Friday was one of the two listed.

In Saturday’s news release describing her as a homicide victim, police said her boyfriend was last believed to be operating the second vehicle, a red 2005 Jeep Grand Cherokee with Maryland plates. It said he was Hispanic, 5-foot-5­ and 170 pounds, with black hair and brown eyes.

Greenbelt, a city of about 23,000, is in northern Prince George’s County, near the Baltimore-Washington­ Parkway and the Capital Beltway.
