Two individuals were sentenced to prison on Friday for causing the death of a pedestrian after their vehicle reached speeds of 130mph in a 30mph zone while they filmed themselves inhaling from a balloon.
On October 12, 2023, a black BMW X5 struck and killed 34-year-old Daniel Mercer in Birmingham’s city center as he walked along a pedestrian crossing at approximately 2:47 p.m. The crash occurred on Corporation Street near the entrance to Snow Hill station, where surveillance footage later revealed the vehicle’s excessive speed and the occupants’ erratic behavior.
Key Points
- ⚖️ Driver Marcus Holloway, 28, received an 8-year sentence for manslaughter and dangerous driving
- 🔑 Passenger Leanne Pryce, 25, was jailed for 4 years for perverting the course of justice
- 📹 Video evidence showed the pair inhaling from a balloon during the high-speed chase
Holloway, who was under the influence of nitrous oxide and cannabis at the time, accelerated to 130mph after Pryce recorded the incident on her phone. The footage, recovered from Pryce’s device, captured Holloway laughing as he swerved through traffic, reaching speeds double the legal limit. Prosecutors argued the video demonstrated a deliberate disregard for public safety.
- First — Holloway’s vehicle was clocked at 130mph by police radar 90 seconds before impact
- Second — Pryce attempted to delete the video within minutes of the crash but failed
- Third — CCTV showed Mercer stepping into the crossing just as the BMW T-boned his vehicle
During the trial, Holloway claimed he was unaware of Mercer’s presence, stating he was focused on evading police. However, forensic analysis of the vehicle’s black box data confirmed he never applied the brakes before the collision. Pryce, who was not directly involved in the driving, was charged after investigators found her attempt to destroy evidence.
| Aspect | Driver | Passenger |
|---|---|---|
| Sentence | 8 years | 4 years |
| Charges | Manslaughter, dangerous driving | Perverting justice |
| Evidence | Speed, drugs, reckless footage | Destruction of evidence |
The case has drawn scrutiny over the use of nitrous oxide, commonly known as laughing gas, which Holloway admitted to using that day. Toxicology reports confirmed the substance in his system, alongside traces of THC from cannabis. Legal experts warn this incident could set a precedent for harsher penalties in cases involving reckless behavior documented in real time.
📋 By The Numbers
- 34 — Age of the pedestrian killed
- 130 mph — Speed recorded before impact in a 30 mph zone
- 8 — Years sentenced to the driver
- 4 — Years sentenced to the passenger
Holloway’s defense argued that his actions were influenced by a temporary mental health episode, but the jury rejected this claim after reviewing the video evidence. The judge described the footage as "chilling" and indicative of a complete disregard for human life. Pryce’s sentence reflects the court’s stance on obstructing justice, even in cases where the defendant is not the primary perpetrator.
💡 Pro Tip
If you witness dangerous driving, prioritize calling emergency services immediately rather than attempting to record it yourself—your footage may be critical evidence, but your safety comes first.
Mercer’s family issued a statement after the sentencing, expressing relief that justice had been served but grief over the preventable nature of the tragedy. The case has reignited debates over stricter penalties for drivers under the influence of legal highs and the ethical implications of recording illegal behavior.
