LOUISVILLE, Ky. (WHAS11) -- He admitted to killing a woman after injecting her with insulin more than six years ago. Now, we're getting a look at David Satterfield's confession to police.

Satterfield turned himself in on Jan. 27, telling police he was responsible for the death of an 84-year-old woman while she was a patient at Parkway Medical Center, in Louisville, on July 4, 2007.

"I think I'm going to join the department of corrections, seeing as I did what I did," Satterfield told police.

"I took an 80 milligram of oxycontin and ended up injecting three people with insulin and one of them died," Satterfield said.

Satterfield told police he was a certified medical technician working rounds at Parkway Medical Center on July 4, when he said he injected Marcelline Vale with three to four syringes of insulin in her leg, knowing she wasn't a diabetic. He proceeded to do the same with two other women down the hall.

"If you have a normal level [of blood sugar] and you get injected with insulin, what's that going to do to you?" an LMPD detective asked.

"It's going to shut your body down," Satterfield said.

Vale died four days later of an insulin overdose. It's unclear why the other two survived.

"What made you key in on these three people?" the detective asked.

"There wasn't really any rhyme or reason," Satterfield said.

So why confess to police after all this time? Police said he was broke, homeless and suffering from a terminal illness.

"I just thought, OK, I can go ahead and admit to what I did, and get a place to stay and eat and not worry about life," Satterfield said.

More than three and half hours into the interview, Satterfield changed his story.

"What is your official statement, right here, right now, David?" the detective asked.

"I didn't do it," Satterfield said.

He'd already said too much.

"If you didn't do it, how did you know all this?" the detective questioned.

Satterfield was put in cuffs moments later and remains at Metro Corrections awaiting his next court appearance on April 25.

As for his other two victims, Metro Police said they have not found enough evidence to bring more charges against him.
