One of the most notorious crimes in Fairfield's history was the subject of a television documentary this week.

The 2005 killings of Tim and Kim Donnelly in their downtown jewelry store by Christopher DiMeo, assisted by Nicole Pearce, was the focus of the series, "Wicked Attraction," on the Investigation Discovery cable network. The new episode was broadcast Thursday night.

DiMeo and Pearce were convicted in a two-month robbery and killing spree in 2005 that included the fatal shootings of the Donnellys in their Post Road store across from Sherman Green.

Pearce, who died three weeks ago in prison from cancer, admitted that she helped DiMeo scout jewelry stores. As they made their way from New York to Connecticut, she kept a phone book on her lap to help find potential robbery targets. She checked out two other stores in Fairfield before the duo settled on the Donnellys' shop, a small store with no surveillance cameras.

DiMeo, spared the death penalty after his conviction in the double homicide this year, fired nine shots from close range at the Donnellys. The couple was tracked down through cell phone records to a $39-a-night hotel in Atlantic City, N.J.

The "Wicked Attraction" on DiMeo and Pearce was titled "Rough Diamond" and is rated TV 14.

Each episode of the series delves into "what happens in the mind of the `average' person when they fall under the spell of a sadistic predator," according to the network. The episode summary added, "Little is known about the chemistry between two people that sparks a killing rampage.

"Forensic psychologists and criminal profilers uncover horrifying clues and reveal the true stories of people driven by love to commit murder."

In addition to the series' panel of experts, the "Rough Diamond" episode included interviews with Fairfield Police Sgt. Edward Greene and Tim Donnelly, son of the slain jewelers.
