LOUISVILLE, KY (WAVE) - He's the medical assistant who surprised everyone including police when he confessed to killing a Louisville nursing home patient seven years ago. But what do we really know about 34-year-old David Satterfield?
Dennis Faulkerburg, a former friend of the alleged killer said as he got to know Satterfiled he didn't like what he was seeing. According to him he was a dark, angry person with a serious alcohol and prescription drug problem.
Satterfield called police claiming he has a terminal illness and wanted to clear his conscience. Then investigators said he told them one other thing - Satterfield admitted he killed 86-year-old Marcelline Vale, a Louisville widow and nursing home patient suffering with Alzheimer's.
He told Louisville Metro Police, in 2007 at the Parkway Extended Care Center, he injected Vale with a deadly dose of insulin.
"I was actually trying to get rid of a cat that I had and he had answered a Craigslist ad on it," said Dennis Faulkenburg of how he first met Satterfield and his roommate a few years ago. "We kind of started hanging out, but there were some issues that arose immediately."
A few months into the friendship, Faulkenburg said Satterfield was nice when he was sober, even speaking fondly of his job as a medical tech, but he claims Satterfield was also an angry drunk, who drank before work and assaulted his roommate at night.
"He (Satterfield) had done some pretty terrible things to him," Faulkenburg said of the roommate. "He had beaten him and he tried to set him on fire." Faulkenburg said he got scared and started moving away from the situation.
He claimed Satterfield started stalking him, even showing up at his work.
"He started leaving these nasty voice mails and he started calling me at 6 at night and didn't stop until 4 in the morning," Faulkenburg said. "He threatened to kill me and threatened to kill his roommate."
The former friend said he called Jeffersontown police, but said because he feared Satterfield, he didn't press charges.
After hearing about Vale's murder Faulkenburg said, "I'm not surprised that he went that violent, but I'm kind of surprised how he did it." Faulkenburg said he feels bad for the victim's family. He said spoke to us in the hopes that the former roommate will tell police what he knows.
WAVE 3 News requested an interview with Satterfield who's being held at Louisville Metro Department of Corrections. He's not interested for now. He is being assigned a public defender.
