Sheffield has always had a reputation as being one of the safest of the UK's big cities.
But there were occasions during 2023 when residents in the city were left horrified after serious crime brought about tragedy.
We have looked back on the last 12 months and the cases to have shocked and caused devastation in Sheffield.
Here are 12 cases investigated or under investigation by South Yorkshire Police. Although all started as murder investigations, some subsequently led to convictions for other serious offences.
Some involved knives - which is one of the reasons why South Yorkshire Police have campaigned and run operations aimed to stop this problem, supported by a South Yorkshire mum, Lisa Theobald, who lost her son to knife crime in 2022, who is urging people not to carry blades.
Several of the crimes have led to prison sentences, including life terms.
Five cases are currently still under investigation by detectives.
