WASHINGTON (WJLA) - Metropolitan police said Friday that they are investigating the death of a 75-year-old woman as a homicide.
By all accounts, Houston was a kind woman full of energy. Those who loved her and used to work with her say she liked to walk - but due to her Alzheimer's, she had gone missing before.
On Monday afternoon, Houston's family explains that she was having lunch with her husband at Torries' on Georgia Avenue just across from Howard University Hospital when it happened again.
So what happened over the next 48 hours?
We know now from police that a construction worker discovered her body in the basement of this abandoned building on Channing Place in Northeast - almost two miles away from the restaurant and just around the block from her home.
The cause and manner of death was asphyxiation and blunt force trauma.
We have confirmed with sources that the possibility that Houston was possible sexually assaulted is part of the investigation. The building on Channing Place is not only close to her home, it was just down the way from where she worked as a receptionist - Old Town Trolley.
Co-workers said they often saw Houston walking along and would escort her home.
Mary Houston was last seen along the 2000 block of Georgia Avenue NW and was listed Wednesday as a critically missing person by Metropolitan Police.
