GREELEY, Colo. -- A woman suspected of using a prepaid mobile phone to make up to 48 false calls for help to 911 was a volunteer firefighter, according to court records.

Caryn Sodaro, 44, of Lochbuie, was a volunteer firefighter in Hudson, according to court records released Monday.

An affidavit said Sodaro allegedly told investigators that after she made phony suicide and ambulance calls to 911 she listened to authorities' reactions on her department-issued police radio.

She also told investigators that she is depressed and thinks of suicide, according to the affidavits.

A deputy documented the 48 calls that Sodaro is accused of making, and exerpts were published Monday on the Greeley Tribune Web site. Among the calls:

The first call on Aug. 4, a woman said she had suicidal thoughts and she was calling from the Carbon Valley Recreation Center in Frederick. Although they were able to track the telephone to a Frederick address, she used a prepaid cell phone, which made it almost impossible to locate the owner.

Sept. 6: A woman called to say she was calling to tell the police where to find her body. She said she was between Lochbuie and Hudson and was going to step in front of the first train to come by.

Oct. 10: A woman called dispatch to say she was at a gas station in Lochbuie and she needed an ambulance. She was not located.

Oct. 17 : A woman called dispatch to report that her mother was not breathing and they were driving on Colo. 52 near Hudson. She said her name was Abby.

Nov. 3: A female caller said she was in a church parking lot in Firestone “to blow her head off, and if she can't do it before the police get there, she is going to make them do it for her.” She was never located.

After many of the calls, the phone number suddenly changed, and sheriff's deputies, Fort Lupton and Lochbuie police found that the new telephone had been purchased at a store in Brighton. From that store, they traced the cell phone to Sodaro.

Sodaro was arrested Friday on suspicion of attempting to influence a public servant, false reporting and resisting arrest.
