LITTLETON, Colo. (CBS4) – A chilling 911 call details the murder of a Littleton man in June by his former business partner. That business partner would then kill himself.

The original murder scene was in Littleton. Police say after that the gunman, identified as Colin Collea, went to a Bear Creek Lake Park observation deck, and before killing himself made a disturbing 911 call.

Collea: “Yes, um, I want to report I shot a guy.”

911 Operator: “How did you shoot him?”

Collea: “I shot him five times.”

911 Operator: “Okay, what’s your name?”

Collea: “My name is Colin Collea.”

The man he shot was his business partner Ken Germain, who was indicted in 2007 for fraud. Lisa Downing was one of his victims.

“It devastated my financial life for the rest of my life, and my children’s life,” Downing said.

It seems his long time friend wasn’t safe either.

Collea: “He uh, was supposed to be watching out for me and he blew all my money.”

911 Operator: “And are you doing okay, Colin?”

Collea: “Not really.”

Collea was still armed but very calm considering what had just happened. He casually told police where the crime scene was and what they’d find at his home.

Collea: “The front door is unlocked; just have the cops go in and there’s a book on the table … it will tell you everything about why, when, where, how.”

911 Operator: “Do you think you’re going to harm yourself?”

Collea: “Oh yeah.”

911 Operator: “I think you can work your way out of this, sir.”

Collea: “No, no, no, no, no. I don’t want to. You know, this is the deal — an eye for an eye. Take a life, you got to give your life.”

The shot can’t be heard on the 911 audio, but Collea’s voice is not heard again.

911 Operator: “Colin, are you with me? Hello? Sir?”

Sources have told CBS4, and the call seems to confirm, that Collea left a note at his home detailing everything. CBS4 is waiting to hear back from Littleton police to see if the case is closed and what was on that note.
