Jeff Call, the major's only child and now a buisnessman in Mississippi, said the book offers a "very objective" look at his father. He has never gone looking for a connection to the Marilyn Sheppard because "it was none of my business."
So, does he believe Conners' theory of the murder?
"I'm not going to second-guess a guy who's a professional," Call said. "He's very accomplished in his ability."
"Tailspin" is a dramaticized version of Call's story, but Conners makes his case for the Sheppard link in a lengthy appendix. Here are some highlights.
-A crowbar confiscated from Call fits as a murder weapon in the Sheppard case, based on the wounds to the victim's head. Call's crowbar had chipping red paint. Chips of red paint were found at Sheppard's house.
-Testimony from a forensic expert indicates Sheppard bit down on the hand of her attacker. Fingerprints taken of Call upon his arrest show an injury to his left index finger consistent with a bite. The mark does not appear on fingerprints taken when Call joined the military in 1943. Investigators found a fresh fingertip bandage at the Lake Placid shootout.
-A tiny triangle of leather was found at the Sheppard site, consistent with a leather flyers' glove of the sort Call was issued. The tear on the glove is consistent with a bite.
-Dr. Sheppard claimed the intruder in his home limped; Call had recently hurt his knee in a car wreck.
-Richard and Betty Jean Knitter saw a man that night near the Sheppard home. Looking at Call's picture 46 years later, Richard Knitter said: "That's the man we saw through our car window that night.
