CRYSTAL FALLS – A woman charged with homicide in the 2014 disappearance of an Iron River man also is under investigation in her husband’s death in February, according to an Iron County court official.

Kelly Cochran, 33, arrived in Iron County from Kentucky late Monday and was arraigned in front of Judge C. Joseph Schwedler in the death of Chris Regan, 53, who has been missing since Oct. 14, 2014.

She pleaded not guilty to felony charges of homicide-open murder, home invasion-second degree, conspiracy to commit dead bodies-disinternment and mutilation, concealing the death of an individual, lying to a peace officer and accessory after the fact to a felony.

“In addition, defendant has claimed responsibility for the death of other individuals which would, if true, make her a serial killer,” Iron County Prosecuting Attorney Melissa Powell stated in seeking a competency evaluation for Cochran.

Cochran declined an attorney, saying she wanted to represent herself. Schwedler directed public defense attorney Geoffrey Lawrence to assist her.

Cochran remains in the Iron County Jail on a $5 million bond.

Future court dates include a probable cause conference and a motion hearing regarding competency to stand trial and criminal responsibility May 31, and a preliminary examination June 6.

In seeking the competency evaluation, Powell said Cochran was voluntarily admitted to an Indiana psychiatric unit in April and has threatened to commit suicide while incarcerated.

Powell’s motion also stated Cochran “has claimed a level of participation in the death of Chris Regan” and is now being investigated in Lake County, Illinois, in the Feb. 20 death of her husband, Jason Cochran.

Cochran made weapons out of her glasses while at the Graves County Jail in Kentucky and threatened to harm anyone who came in contact with her, according to the motion.

She was arrested April 28 by U.S. marshals and the Kentucky State Police in Wingo, Kentucky, after fleeing her home in Merrillville, Indiana.

Iron River Police Chief Laura Frizzo has said Cochran – believed to be one of the last people to see Regan – left Michigan after her residence was searched in March 2015 and had since been living in Merrillville with her husband.

He died Feb. 20 in Merrillville, according to an obituary from Burns Funeral Home in Crown Point, Indiana.

Regan’s vehicle was found three days after he was reported missing in a Michigan Department of Transportation carpool lot at Bates-Amasa Road and U.S. 2 in Bates Township.

A search of the Caspian Pit in Leo Remondini Jr. Memorial Park in Caspian last October that involved the FBI and a host of other law enforcement and forensic agencies yielded “items of significance,” Frizzo said.
