Mother is Suspect in 'Very Bloody' Death of Her Two Children, Police Say

Two of her other children and one adult were wounded at a Maryland townhouse.

Jan. 17, 2014— -- Authorities in Maryland are investigating a double homicide discovered this morning in which two young children were found dead and two other children wounded at a townhouse that police described today as a "very bloody" crime scene.

Police in Montgomery County have taken into a custody a 28-year-old mother of the four children believed to be the sole suspect in the case, they said today.

The turmoil in a Germantown, Md., neighborhood began Thursday night, when police responded to a 911 call by a neighbor reporting a child left unattended in a vehicle, Montgomery County Police Captain Jim Daly told ABC News.

By the time police arrived, two women exited the townhouse, retrieved the child, and re-entered the home. Police investigated and arranged for child protective services to visit the home of the child.

This morning, around 9:30 a.m., police received another 911 call from a resident of the same neighborhood reporting blood on the outside of a vehicle and a knife lying outside of the vehicle, prompting police to enter the residence. When they entered, the 28-year-old woman fled out of the back of the home and was apprehended by police, authorities said.

The woman's name has not been released. Identities and ages of those involved will be released following next of kin notification.

Police found two children dead in the upstairs part of the home, as well as two children and one 21-year-old woman who suffered injuries. She is not believed to be a family member but is believed to have lived at the residence, police said.

Two of the children, along with the 21-year-old woman, were transported to local hospitals for treatment.

Daly would not say what types of injuries the children or woman sustained, but police characterized the crime scene as very bloody. All of the children are believed to be no more than 10 years old. Police have not given any information about a possible motive.
