PC Mills dealt with Ken and Leanne Barlow when they reported a drunken Peter Barlow missing in July 2012. She took a description and worried the two when she heard that Peter had tattoos and left the office to make a check. Returning, she told them that a dead man had been found that morning who was of a similar description. She took the two to a mortuary where they inspected the body, only to find that it wasn’t Peter.
Six months later she conducted enquiries in Coronation Street after Kirsty Soames fell downstairs in a row with Tyrone Dobbs and claimed that he had pushed her. She interviewed Eileen Grimshaw and Deirdre Barlow who both gave evidence that seemed to back up Kirsty’s lies.
In July of the same year, she conducted a search of Nick's Bistro with colleague PC Burke after receiving an anonymous tip-off that drug dealing was taking place on the establishment's first student night. In truth, the call had been made by David Platt who had discovered that his wife Kylie and half-brother and bistro co-owner Nick Tilsley had had a Christmas Day fling and was out for his revenge. No drugs were found but the damage was done as Weatherfield Gazette journalist Naila was on the premises and wrote up a damaging story for the paper.
On Christmas Day, Mills and a male colleague were on duty when they witnessed a scuffle between a drunken Kylie Platt and Rovers' barmaid Tina McIntyre. Kylie had just been barred from the pub by landlady Liz McDonald for taunting Tina about being dumped by Tommy Duckworth. As she was escorted off the premises, Kylie made a pass at Rob Donovan and proceeded to attack Tina when she turned the tables were turned and taunted Kylie about sleeping with both David and Nick. The officer arrested Kylie on suspicion of assault and she spent the night in police custody, but was subsequently released without charge.
In January 2015, Mills and a colleague located Steve McDonald and Michelle Connor after he wandered off from the scene of an accident. Steve was driving the minibus taking Carla Connor and the Underworld staff to an award ceremony at the Marbury Hall Hotel, but he lost control of the vehicle as it flipped off the road when he had to swerve to avoid ploughing into a car containing boy racers. The officers needed to interview Steve about the accident and followed the casualties to a local hospital. However while he was giving his statement, Steve suffered a panic attack and medical staff were called to intervene.
In May of the same year, she held back the crowds from the burning Victoria Court site but Maddie Heath slipped under the tape when her back was turned and was injured when a secondary explosion occurred in the Builder's Yard. Two months later, she was with a group of officers that conducted a raid on the Dog & Gun where Bethany Platt was drinking with Callum and Gemma Winter. Callum had only just given Bethany a packet of drugs to deliver and she managed to pass it to Gemma. When she tried to go to the toilets alone, PC Hall, leading the raid, insisted that another officer accompanied her. Mills was the one who did so and Gemma was duly arrested and let off with a caution.
In April 2016 she called at 11 Coronation Street with another officer and broke the shocking news to Eileen Grimshaw that her ex, and Jason's father, Tony Stewart, had been found dead in his flat by his work colleagues, having lain for three days undiscovered following a heart attack.
- The character was credited as "Police Officer" for her first nine appearances and only named in April 2016.
