A 69-year-old man held this weekend in an Arizona jail is a person of interest in the disappearance of three separate women over several years, PEOPLE learns.

Mohave County sheriff’s officials told PEOPLE they believe Robert Carnochan is connected in some way to the disappearances of Verna Clayton, who was last seen in 2008, and Neva Lindley, who was last seen in 2011 – and that he is possibly connected to the disappearance of Nancy Hartz, who was last seen in 2015.

A search of his home revealed evidence that links him to their cases, sheriff’s officials tell PEOPLE.

All three women lived within a roughly 100-mile radius and are around the same age, officials said. All three women had been dating a man they met online, though police would not confirm this man was Carnochan. Hartz sold her home and was closing her bank account just before disappearing.

Carnochan was located by authorities in April, in Yucca, with another woman, according to the sheriff’s office.

He was allegedly found with “several aliases and firearms,” and authorities soon confirmed he was actually a Canadian citizen who allegedly illegally immigrated into the U.S. more than 20 years ago, officials say.

Carnochan is currently being held in the Mohave County jail on unrelated charges of forgery, identify theft and weapons violations, according to records. It was not immediately clear if he had entered a plea to those charges.

Carnochan told authorities that he last saw Hartz alive when he dropped off her in March at a business in Kingman.

Hartz’s daughter, Denise Baggs, told the AP she attends each of Carnochan’s court appearances and no longer believes her mother is alive.

“I want him to tell me where he left my mother,” she said.
