Bellevue Blood Spatter Exposes Second Killer | The New Detectives | S7 E17

A rope, a blood trail, and a trash can of DNA expose teen killers. The New Detectives follows three chilling cases where forensics cuts through lies. In Cambria County, Pennsylvania, 15-year-old Micah Pollock vanished after being seen with 16-year-old Andrew Callahan near an abandoned strip mine. Heavy rain complicated the search until a trash can with human blood and, later, a cadaver dog led investigators to a beaver pond where Micah’s bound body was found. With ballistics inconclusive and no blood on Callahan’s clothes, criminalist Bruce Tackett compared the clothesline on Micah’s ankles to rope from the Callahan home and car, finding identical construction and core fibers under the microscope. Confronted, Callahan claimed an accidental shooting while hunting, but powder burns and pellet trajectory proved a close, upward shot that contradicted his story. He was convicted of first-degree murder and sentenced to life without parole. In Bellevue, Washington, 20-year-old Karen White was found strangled in a park. Hours later, her parents Regina and Walter and sister Janet were discovered bludgeoned and stabbed at home. Teen Alex Barrani confessed, but bloodstain expert Ross Gardner reconstructed the scene and identified cast-off from both a knife and a blunt object, plus a wall void indicating a second attacker. A rope found in David Anderson’s car was the same type used to strangle Karen. Both teens were tried as adults and received four consecutive life sentences. In Phoenix, Arizona, 13-year-old Brad Hanson disappeared. Rumors pointed to classmate Jeremy Bach’s jealousy. Detectives seized the family’s curbside trash can; pooled blood inside matched Brad through his parents’ DNA. Firearms testing showed the .357 Magnum’s hammer block and a 10.25-pound trigger pull, undercutting an accidental discharge claim. Tried as an adult, Jeremy was convicted of second-degree murder and sentenced to 22 years. Brad’s body has never been found. Some names have been changed. This episode shows how rope comparison, bloodstain pattern analysis, DNA profiling, and firearms testing reveal the truth when excuses fail. #TheNewDetectives #TrueCrime #ForensicScience #BellevueMurders #MicahPollock #BradHanson #RopeEvidence #BloodstainPattern
