Dying to Swing

First, in Evansville, Ind., police responded to a report of a possible kidnapping and murder the night of October 19, 2021.

Officers were met by Cynthia Weinzapfel, who alleged she agreed to meet Heidi Carter at her home to help her clean ahead of a landlord inspection, according to probable cause documents reviewed by A&E Crime + Investigation.

Upon entering the residence, Weinzapfel said she noticed Carter, 36, had what appeared to be blood on her shoes and a handgun on her person. After cleaning two rooms, Weinzapfel claimed she heard a woman in a back room crying for help and that she subsequently sat on a dead body buried beneath a pile of blankets, the documents read.

Weinzapfel panicked and tried to leave. She said she was briefly held captive by Carter and her boyfriend, Carey Hammond, 46, but was later able to escape and run for help. She encountered an Indiana State Trooper in the neighborhood who in turn called police. Hammond engaged in a standoff with police and was fatally shot on the scene, while Carter was arrested and brought in for questioning, according to authorities.

Officers investigating the property discovered a kidnapping victim, Amanda Siebe, with visible injuries, tied to a bed frame in the back of the house. She told authorities she was raped and that her boyfriend, Tim Ivy, was killed and hidden beneath a pile of blankets in the home. Police found Ivy, 50, bound with duct tape, beaten and strangled to death, according to reports.

During police interviews, Carter said she met Siebe on a dating app and that the victim agreed to bring her boyfriend, Ivy, over for sex while Hammond was at work. But Hammond came home and walked in on the trio engaging in intercourse. In response, he beat Ivy and Siebe with a baseball bat, according to authorities. Police determined Carter helped Hammond restrain the victims before Hammond sexually assaulted Siebe while she was bound.

“He raped me. Heidi [Carter] was there, too. She wasn’t touching me, but she was there and encouraging him,” Siebe told investigators. “They told us the entire time that that’s what they were gonna do. They were gonna kill us.”

Hammond beat and fatally strangled Ivy with a belt, authorities said. He and Carter then moved his body to another room and covered it with a blanket. Carter argued she was only “pretending” to help Hammond restrain the victims to “appease” him, according to reports.

Carter was charged with murder, criminal confinement with a firearm, rape, intimidation with a firearm, felon in possession of a firearm, assisting a criminal and abuse of a corpse. She was convicted of murder, felony rape and felony criminal confinement and sentenced to 65 years in prison in February 2023.

Teen Wanted to ‘Know What it Felt Like’ to Kill

In Grand Junction, Colo., on February 28, 2021, officers were called to help pull Brian Cohee Jr.’s car out of the Colorado River.

The 19-year-old claimed his vehicle accidentally veered off into the water, per the police report obtained by A&E Crime + Investigation. A responding officer noticed what appeared to be blood on Cohee’s rear bumper, but the teen denied having any injuries or knowledge of the matter found on his car. Police let him go. The next day, Cohee’s mother called 911 to report she found a severed head in a garbage bag in her son’s closet.

Cohee met investigators on the scene and confessed there was a human head and hands in his bedroom, according to authorities. He admitted to killing Warren Barnes, a 69-year-old transient man, on the night his car fell into the river. He told investigators he was driving around that night when he saw a homeless person beneath a canvas sleeping underneath a highway overpass, so he retrieved a kitchen knife from his glove box and ambushed the victim, stabbing him in the neck.

Cohee described in detail how he decapitated Barnes and sliced “open his belly to see ‘his guts,’” the report states. He admitted he dismembered the victim’s body, put his head in a kitchen trash bag and his hands in storage bags and hid the remains in his closet at home. The rest of the body parts were dumped under a bridge and into the Colorado River.

Cohee said he wanted to “know what it felt like” to kill and spent six months planning his first and only murder, according to police. Although he confessed he previously decapitated and killed a cat in 2018, he told detectives, "I'm not a serial killer, by all means.” Cohee also has a history of major depressive disorder and autism.

He was convicted of first-degree murder and sentenced to life in prison in February 2023.
