Quick Summary

At Bolton Coroner's Court, an inquest has revealed that Zak Bolland, who murdered Michelle Pearson and her four children by setting their home on fire in December 2017, could have been arrested hours before the attack. Police officers missed the opportunity to apprehend him when they failed to make the arrest immediately after receiving a threat from Bolland against the family's safety. Michelle Pearson died nearly two years later due to severe burn injuries sustained during the arson attack.

Story summary

In December 2017, Zak Bolland and his associates were involved in a series of violent threats against Michelle Pearson's home in Salford after a feud with her son. These incidents included vandalizing the house and threatening to set it on fire. At about 12:40 AM, Bolland attacked the property again, prompting Michelle Pearson to call 999. A probationary police officer named PC Mick Grundy was dispatched but did not arrest Bolland despite the threats. Tragically, a few hours later, Bolland petrol bombed the house, killing Michelle and her four children: Demi (15), Brandon (8), Lacie (7), and Lia (3). The inquest held at Bolton Coroner's Court revealed that an arrest could have prevented this tragedy. Michelle survived the fire with severe injuries but passed away more than a year later, aged 37.
