The investigation into the murder of teenager Paul Sorrel, who was found shot dead in a park last week, continues.
Paul's grieving mum, Emma, visits the crime scene.
Emma is joined by her brother Gary and his young son Bobby.
It all proves too much for Emma, who is comforted by Family Liaison Officer, PC Leon Taylor.
The Sun Hill cops are on hand to secure the crime scene, but are they any closer to finding Paul's killer?
DC Jacob Banks and DS Max Carter follow up a lead…
Jacob approaches Devon Marshall, who police informant Jasmine says she saw with Paul on the night he was shot.
The officers move in to question Devon.
Convinced Devon is afraid to reveal what really happened on the night Paul was killed, Max and Jacob offer him witness protection in the hope he'll give them more information.
Elsewhere, Commander Lisa Kennedy heads up a public appeal for information about Paul's murder.
But the crowd soon start jeering and shouting that the police know who killed Paul.
Devon's in the audience – will he speak up about what happened to Paul?
Pressure is mounting on the Sun Hill officers to catch the killer. Will they get the breakthrough they need? Watch the action unfold on The Bill on Thursday 18 March.
