A true crime program airing tonight on Investigation Discovery will tell the story of the 2001 death of Kathleen Peterson from the perspective of Kathleen's daughter, Caitlin Atwater.

Kathleen Peterson's husband Michael Peterson (left) was convicted in 2003 of murdering her in their Durham home.

Peterson is currently seeking a new trial. A hearing on that is scheduled for next month.

"The Devil You Know," airing at 10 p.m., features interviews with Atwater, as well as Art Holland of the Durham Police Department, and Fred Atwater, Kathleen's first husband.

The episode airing tonight is called "Stairway to Hell." (The murder trial was the subject of a 2004 documentary by Jean-Xavier de Lestrade called "The Staircase.")

"The Devil You Know" describes itself as a series that "delves into the secret lives of men and women who masquerade as law-abiding citizens but, behind the charade, are hiding deadly intentions from their loved ones." The shows offers first-hand accounts from friends and family members to tell the stories.

Investigation Discovery airs on 251 and 1251 on Time Warner Cable. On DirecTV you'll find it on 285 and 1285; AT&T U-Verse has it on 260 and 1260; Dish Network has it on 192.

Larry Pollard, a lawyer-turned-businessman and former neighbor of convicted murderer Michael Peterson, has scheduled a news conference Thursday morning to try to bolster his hypothesis that an owl killed the novelist’s wife.

Pollard has insisted for more than four years that a neighborhood owl swooped down on Kathleen Peterson the night in 2001 that she was found dead at the base of a staircase in a pool of blood.

Prosecutors and police have put little stock in his theory, and Peterson’s defense lawyers did not mention the possibility during trial, but Pollard has continued to pore over investigative reports.

One SBI evidence report, Pollard says, mentions a microscopic feather found in Kathleen Peterson’s hand with some of her hair.

Pollard says that evidence was not listed in subsequent reports. He wants the case reopened. He'll make his case again at 11 a.m. Thursday outside the Durham County courthouse.

District Attorney David Saacks declined to comment about Pollard’s claims. Jim Hardin, the former DA  who tried the case, has said before that there was no evidence of an owl attack.

The old Mike Peterson place in Forest Hills has a new owner.
