Reported missing on March 9 by her daughter, 38-year-old Diana Alejandra Keel was last seen by her husband on March 8, Nash County Sheriff's Office said.
Keel's employer said the nurse had not proven to work in recent days. The Sheriff's office said her body was found about 30 miles from her home.
After an autopsy on Wednesday, police confirmed Keel's identity and said her death was being treated as a murder.
Police questioned Keel's husband, Rexford Lynn Keel, on Tuesday May Miss Strickland in Nash County Sheriff's office said. He has not been burdened in his wife's death and has since been released. Keel has not responded to CNN's request for comment.
Investigators also take a second look at Keel's first wife Elizabeth Edward Keel's death, which died in 2006 in the same home Keel lives today, according to a statement from the sheriff's office.
Keel did not T report his wife's disappearance, Nash County Sheriff Keith Stone said. Keel said his wife would often leave his Nashville, North Carolina, several days at a time, according to Stone.
She would not leave her children
But her family said that the mother of two would not have left their children behind. "My sister would not leave her children alone," said Keel's brother Mauricio WRAL. "She's happy, she cares, she's a good mother, she's the best sister ever. She's like a guardian angel."
Stone said at a press conference on Wednesday that he had been told that there were some "difficulties" in Keel's marriage. Sten also said that Rexford Lynn Keel collaborated with the police.
Keel's first wife Elizabeth Edward Keel was killed in an accident by the medical officer's office, Nash County Sheriff Office said. An autopsy indicated that she died after falling and banging on the forehead on the corner of concrete steps at the front of the home. Strickland told CNN that the detectives were working with the FBI and other local agencies to investigate the death of both women.
"There is definitely a killer on the loose and we do everything we can," Stone said at a press conference Wednesday.
