Hashtag Homicide

Every post leaves a trace

A teenager who trusts a friend he met through online gaming. A travel vlogger whose posts suddenly stop. A message, a location check-in, a confession posted to the world.

About the series

Hashtag Homicide follows seven real cases from Britain and the United States in which social media left the trail that investigators followed to the truth. Detectives, journalists and the families of the victims explain how each case was solved — and what changed afterwards.

The seven cases

01

The Online Friend

England · A mother warns that a stranger on her 14-year-old son's online gaming server is taking control of his life, but help comes too late. The boy's tablet and his friends' messages expose a calculated lie; the killer admits murder and is jailed for life. His mother's foundation now teaches online safety in schools.

02

The Road Trip

USA · A young travel vlogger shares a cross-country road trip day by day, until her posts suddenly stop. Her family's appeal goes around the world, and a stranger's travel video helps lead investigators to the truth. Her case has since inspired new laws in Utah and Florida.

03

Live on Camera

San Diego · A TikTok creator with a large following is arrested after two people are killed in a downtown apartment. Livestreams, a hidden tablet and a recording on his own phone show the crime was planned. He is serving life without parole.

04

#JusticeForDaisy

California · When 19-year-old Daisy is killed and the prime suspect disappears, her best friend turns to TikTok. The viral campaign brings the tip that locates him in Mexico. He is convicted of first-degree murder and sentenced to 26 years to life.

05

Blocked

Washington State · A software engineer who mentors newcomers to tech on an audio-chat app is targeted by a listener who floods her with calls and messages from ever-changing accounts. The case ends in tragedy — and the state strengthens its stalking law.

06

The Car Club

Idaho · An online feud inside a Facebook car club spills into real life, and the club's 23-year-old founder is killed. Minutes later the suspect confesses online. Posts, an emergency call and dash-cam footage lead to a conviction and a sentence of 45 years to life.

07

Last Location

Wigan, England · When an 18-year-old student fails to return from a walk, one geotagged Snapchat points police and her friends to the right park. Social-media appeals, forensic science and a tip from the public lead detectives to the man responsible.
