During a search of Allen's home on Oct. 13, 2022, officers found knives and guns, including a "Sig Sauer, Model P226, .40-caliber pistol," the probable cause affidavit said.

Indiana State Police's analysis of Allen's gun "determined the unspent round located within two feet" of one of the victims "had been cycled through Richard M. Allen's Sig Sauer Model P226," the probable cause affidavit said.

"When asked about the unspent bullet, [Allen] did not have an explanation of why the bullet was found between" the girls' bodies, the probable cause affidavit said.

Investigators also cite a witness who saw Allen walking with "clothes that were muddy and bloody," according to the probable cause affidavit.

Video from one of the victim's phones shows a man on the trail wearing dark jacket and jeans... Investigators said in the probable cause affidavit that they believe Allen is the man seen on the video.

Allen told investigators on Oct. 13, 2022, that he wore jeans and a blue or black Carhartt jacket that day, according to the probable cause affidavit. Allen's wife confirmed to police that he owns a blue Carhartt jacket, the document said.

I have to say, my money was on DNA evidence before this stuff came out. I thought the police must have had pretty solid evidence to make an arrest out of the blue after this many years. Apparently the Kline stuff was all a red herring; still don't know what that river search from a few months ago was about, though. Also notable that the state police seem to have been handling most of the important stuff, not the local cops.
