A true crime documentary series has left viewers horrified, with all seven episodes now available to stream for free on Channel 5. The programme, titled Murder Suspect No.1, follows homicide detectives as they investigate violent deaths, building a picture of each case from the first emergency call to the courtroom.
New episode focuses on M40 confession
The latest instalment, which aired on Monday, November 2 at 9pm on Channel 5, centres on a man who confesses to murder while walking along the hard shoulder of the M40. After a woman is found dead at a home in Havant, detectives face the task of establishing what happened when their suspect refuses to speak.
Channel 5's synopsis reads: "A man walking along the hard shoulder of the M40 confesses to murder; police discover a woman dead at her home in Havant; and detectives must prove what happened when their suspect refuses to talk."
Viewer reactions and comparisons
The episode prompted strong reactions online, with one viewer writing: "I literally nearly threw up thinking what she went through." Another posted on social media: "Wow, what a horrific way to die," and later added: "Be prepared." Others remarked: "Wasn't it horrendous" and "Was absolutely brutal."
For fans of 24 Hours in Police Custody, the series offers another close look at the work that goes into a murder investigation. Since launching in 2025, it has drawn comparisons with that programme, with viewers describing it as "as good as 24 Hours in Police Custody".
Streaming and future episodes
The latest instalment aired after the recent run of Major Crimes Unit ended last month. It also marked the return of Murder Suspect No.1, following a gap since its last new episode earlier this year. All seven episodes broadcast so far are available to stream free on Channel 5 online, covering cases that include an axe attack and a one-punch killing.
The series follows detectives as they gather evidence, question suspects, and work to establish the truth. Channel 5 describes it this way: "We follow top homicide teams as a series of violent murder investigations unfold."
Murder Suspect No.1 does not appear in next week's television listings, and a date for the next new episode has not been confirmed. In the meantime, viewers can watch every instalment released to date back-to-back.
