-- The "disturbing" voicemail a Minnesota woman received from the phone of her missing husband has been released, and she and investigators believe that it may contain important clues into his mysterious disappearance.
Kareen McCabe received the bizarre voicemail on Sept. 7 at 2:28 a.m., according to Mounds View Police Department Chief Tom Kinney. He told ABC News that Kareen had been away in California at the time while her husband Henry McCabe had stayed behind in Mounds View, Minn.
The voicemail, which was obtained by ABC News, features two minutes of undecipherable noises, including what sound like growls and moans of pain. Near the end of the voicemail, the sounds suddenly stop and a voice can be heard saying, "Stop it."
Police have been "unable to make any definite conclusions about the disturbing voicemail," Kinney said, adding that 31-year-old Henry McCabe was officially reported missing the following morning and that no one has reported seeing him for nearly four weeks.
Kinney added that the police department recently sent the audio recording to a local FBI office for "further analysis and cleaning up."
Kareen McCabe told ABC affiliate KSTP that she believes sounds in the voicemail are from her missing husband.
"I try to picture where he was, what it might've been like, what circumstances would've made him sound like that," Kareen McCabe told KSTP.
Henry McCabe was reportedly last seen by an acquaintance who told police that he went with McCabe to a nightclub the same night Kareen got the voicemail, according to the police chief.
"The acquaintance told us that he dropped McCabe off not too far from the club a little after 2 or so in the morning at a local gas station's convenience store," Kinney said. "There's been some searching done by both volunteer groups and our own law enforcement personnel along possible routes he perhaps may have walked if he tried to get back home. Nothing of any significance has been discovered yet."
The police chief added that investigators "aren't ruling out any possibilities, whether it be that he disappeared on his own, or if there was some kind of accident involved, or if there was some other intentional act of harm someone tried to bring upon to Henry."
In addition to assistance from the FBI, the Minnesota Bureau of Criminal Apprehension (BCA) is also providing investigative help to the Mounds View Police Department, which is the lead law enforcement agency handling the missing person case, Kinney said.
The McCabes have been married for 11 years and their two children -- ages 1 and 10 -- are staying with Kareen's mother in California while she works with investigators to find her husband, according to David Singleton, who runs Minnesota Community Policing Services (MCPS). MCPS is a non-profit agency that has acted as a mediator between Kareen McCabe and law enforcement agencies, Singleton told ABC News.
The police chief said that Henry McCabe is an African American male, who is about 5-feet-11-inches tall and who weighs about 168 pounds. He asks that anyone with any information regarding the open case please contact the Mounds View Police Department at 763-717-4070.
