SANTA FE, N.M. — A New Mexico man may have been living in a house with a woman’s dead body for several weeks, authorities say.

The body of Elvira Segura, 67, was found in a blood-spattered bathroom of her Nambe home on Sept. 27, according to New Mexico State Police. Nambe is a quiet community north of Santa Fe.

Police are looking for Robert Mondrian-Powell, 57, in connection with Segura’s death, according to a statement released Thursday. Court documents say Mondrian-Powell had lived with Segura, a former Santa Fe librarian.

Police have not released a cause of death or labeled Segura’s death a homicide.

A car registered to Segura was found abandoned in Las Cruces on Sept. 24, with the windows rolled down and the keys still inside, according to a search warrant affidavit filed in Santa Fe District Court. While performing a welfare check at Segura’s home three days later, officers noticed a bad smell and saw flies in the house, according to the affidavit. They crawled through an open window and found Segura’s body as well as a dead dog in a bedroom, the documents said.

According to an autopsy, the level of decomposition revealed that the woman had been dead for weeks.

Two different neighbors told police that they heard gunshots at the house about three weeks before the welfare check. Officers also found what appeared to be blood between a greenhouse and the kitchen, according to the affidavit.
