WASHINGTON (WUSA9) — The skeletal remains of three females were discovered in an apartment building in SE DC, DC police say.

Construction workers discovered the first set of remains in a crawlspace on Wednesday. DC police tell WUSA 9 the crawlspace is in an apartment building on the 100 block of Wayne Pl SE.

“Well they were shocked but they didn't know what number to call or something like that,” said William Bailey.

Bailey lives near where the discovery was made. Shocked, Bailey says the construction workers had asked him what to do.

Bailey says he told them to call 911 after they told him what they had found.

“The workers came out and said they found a skull,” said Bailey.

DC Police used the words: Skeletal remains.

On Friday, the DC Medical Examiner confirmed the remains found are human remains.

Then on Saturday, two additional sets of skeletal remains were recovered nearby.

The DC Medical Examiner says all three are female.

The investigation is ongoing.

Bailey called the discovery “unnerving.”

"At least somebody will find that their relatives... are passed away and they don't have to worry about looking for them for them anymore so there will be some kind of closure for the family, you know,” Bailey told WUSA 9.

Anyone with information about this case is asked to call the police at 202-727-9099.
