At 7.26am 19/09/2021 the force was called in relation to concerns for the safety of a man in Killamarsh.

Four minutes later, when officers arrived at the house in Chandos Crescent, they found the bodies of 35-year-old Terri Harris, her two children, 11-year-old daughter Lacey Bennett and 13-year-old son John Paul Bennett, and Lacey’s friend Connie Gent, also 11, from Sheffield.

One man has been arrested in connection with their deaths and remains in police custody.

A murder investigation has been launched. At this time, we believe the incident to be isolated, and we are not looking for anyone else in connection with their deaths.
