The 57-year-old woman was found by police responding to a report of a foul odor coming from the home on Avenue N in Midwood just before 9:45 p.m.
Officers found the victim's body in in the basement in a severe state of decomposition. She is estimated to have been dead for at least a week.
Police say she had been stabbed multiple times in the back.
The officers discovered a note on her body, purportedly written by her husband, claiming that she was casting spells on him.
Detectives were looking for the husband, who has not been seen recently. As a result of the ongoing investigation, a person of interest has been taken into custody, but it not clear who that person was.
Identification of the victim is pending proper family notification.
