WASHINGTON - D.C. police have made an arrest in connection to the murder of a woman found in a dumpster in Northeast.
What we know:
Donella Bryan was a 62-year-old mother, grandmother and a longtime dental assistant in the area.
FOX 5 first reported on this murder back in April and now, police say they have made a break in the murder case.
Detectives say 58-year-old Richard Dyson is now charged with her murder.
Dig deeper:
According to court documents, Dyson killed Bryan, bought a plastic red bin and then his neighbor, alleged accomplice Perry Brown, allegedly helped dump her body in the bin inside the dumpster behind Heckigner Mall on Maryland Ave., NE.
FOX 5 interviewed Brown back in April. He was not considered a suspect at the time.
Brown was found dead inside his apartment with a white substance next to him on Wednesday.
Around the same time, police arrested Dyson for allegedly murdering Bryan.
Police searched Dyson’s apartment and they say they found what appeared to be drops of blood in the entryway.
