ADELPHI, Md. (WUSA9) -- A 98-year-old woman was found dead in the 2400 block of Tecumseh Street in Adelphi, Md. Sunday morning.
The woman, who has not been identified was found behind the Mary Harris "Mother" Jones Elementary School, authorities said.
Prince George's County Police say the cause of death is still unknown and is being called a death investigation as of now.
Neighbors told WUSA9 Nikki Burdine, the woman had lived on the block for years.
"It really caught us by surprise," a neighbor, Louis Velis said. "This is a really quiet neighborhood and when you see that many police cars in the area, you know something major happened."
An autopsy will be performed Monday, authorities said.
