40case filesUpdated Jul 18, 2026
Casepin holds 40 cold cases in the US. A cold case is an unsolved case whose active investigation has stalled; the label comes from each file's status field and changes the day the record does.
COLDListenCumming, Georgia · 2018
Tamla Horsford, a 40-year-old mother of five, died from a fall at a home in Cumming, Georgia, during a gathering on November 3-4, 2018; two separate investigations ruled her death accidental, though her family has disputed that finding and pushed for further inquiry.

Cheri Jo Bates, an 18-year-old Riverside City College student, was stabbed and slashed to death on campus grounds on October 30, 1966, after her car was deliberately disabled. The case remains officially unsolved, though it has drawn attention due to a contested theory linking it to the later Zodiac Killer murders.
COLDListenAlexander, Arkansas, United States · 1987
Two Arkansas teenagers, Don Henry, 16, and Kevin Ives, 17, were found dead on railroad tracks in Alexander, Arkansas, on August 23, 1987, after being struck by a freight train. Initially ruled an accident, a grand jury later declared the deaths "probable homicides," and the case remains unsolved amid allegations of witness deaths and official misconduct.

Don Lewis, a Tampa, Florida, businessman and co-founder of an exotic-animal sanctuary, disappeared on August 18, 1997, at age 59, after leaving home on an early-morning delivery; his van was found two days later at an airport 40 miles away with the keys inside. He was declared legally dead in 2002. No one has been arrested or charged, and investigators have said they have no evidence a crime occurred; the case drew renewed public attention after the 2020 documentary series Tiger King.
COLDListenLowndes High School, Valdosta, Georgia · 2013
Kendrick Johnson, a 17-year-old Georgia high school student, was found dead inside a rolled-up gym mat in January 2013. Officials ruled the death an accident, but his family pursued independent autopsies, civil lawsuits, and a federal review, alleging murder and cover-up; no criminal charges were ever filed.
COLDListenPrairie Village, Kansas · 2019
Angela Green vanished from Prairie Village, Kansas, in June 2019, and police and the FBI continue to seek information about what happened to her.
COLDListenRichmond, Indiana, United States · 2001
Marilyn “Niqui” McCown disappeared from Richmond, Indiana, in July 2001, and police continue to investigate without an arrest or charge.
COLDListenCocoa Beach, Florida, United States · 1994
Amy Gellert was fatally attacked outside her Cocoa Beach home in 1994, and the Brevard County Sheriff's Office continues to list the homicide as unsolved.
COLDListenAliquippa, Pennsylvania, United States · 2018
Rachael DelTondo was shot outside her home in Aliquippa, Pennsylvania, on May 13, 2018; no one has been arrested, and the district attorney said in May 2026 that the available evidence was insufficient to charge anyone.
Pacific Northwest, United States (multiple related incidents across the U.S. and abroad) · 1970s
Following the unsolved November 1971 D. B. Cooper hijacking, more than a dozen copycat hijackers across the United States (and several abroad) attempted similar extortion-and-parachute schemes through 1972, prompting aviation security reforms including the "Cooper vane" and widespread metal detectors.
The files run from 1639 to 2019. The 1980s hold the most, with 7 files. The oldest is Lynching of Charles Lockwood, from 1886.
They are spread across 26 states and regions; the most are in Georgia (4), Florida (4) and Indiana (4). By type, the largest groups are murder and homicide cases (25), disappearance cases (10) and kidnapping and abduction cases (7).
14 files of the 40 have coverage attached: 32 videos, podcasts and documentaries from 13 creators. The most covered is Death of Tamla Horsford, with 10 items to watch or hear. Kendall Rae, Dateline NBC and Dr. Todd Grande have covered the most of them.
Every file is written from cited sources and pinned where it happened, and every person named carries the legal status the record gives them. If you hold information about an unsolved case, contact the investigating agency named in its file rather than posting it publicly. Families and anyone involved can request a correction from any file.
