Police are investigating the circumstances of a deadly explosion in Bristol that kills a 35-year-old woman and her former partner. According to reports, Jo Shaw dies on 3 May after her ex-boyfriend, Ryan Kelly, is also killed at the scene. The incident is described as a suspected murder-suicide in which Kelly allegedly forces his way into Shaw’s home and detonates an explosive device, described by some outlets as a grenade. The reporting also says Shaw had previously reported Kelly for stalking and assault, and police were investigating or had been made aware of concerns about his behaviour. Emergency services respond following reports of an explosion, and investigations are underway into what happened before the blast, how the device was brought to the property, and whether there were any prior warning signs that could inform protection measures. Police have not concluded the investigation in the accounts provided, and the focus remains on establishing the facts of the incident.
