PC Terry Warren escorted Laurel Thomas and Rhona and Leo Goskirk home after Laurel was carjacked . He told Marlon Dingle that he'd radioed the car details back to the station and tried to calm them all by stating that he believes the Carjacker would have drove to a quiet place then let Laurel and Leo out of the car.
He returned later in the week to quiz Cain Dingle after being informed that he had had possession of the car. A suspect was later arrested and he visited Laurel again for her to look over an ID parade, but she could not pick out the suspect.
In March 2014, PC Warren attended Hotten General Hospital after Gemma Andrews was admitted with head injures. After Gemma's death, PC Warren talked to Gemma's friends Belle Dingle and Sean Spencer to get their version of events leading up to Gemma's death.
