Yvonne's career almost comes to an end when she faces criminal charges due to the death of a young man she was trying to arrest after she struck him with her ASP. An inquiry is held, and she is acquitted of all charges when it is ruled she acted in self-defence. Yvonne was also connected to Shirley Moss, in lots of bad ways but lots of good as well. Yvonne risks contracting HIV from delivering Shirley's baby after rescuing Shirley from a suicide attempt. Yvonne later leaves Sun Hill to become a Sergeant at another station working with young offenders. DC Scott Henderson is DCI Burnside's right-hand man on his investigation team at crime OCCU, who first appears shortly after Burnside's return in 1998. Henderson did not appear in any of the non-Burnside episodes, and only made five appearances in the show over the period of five months from December 1998 to April 1999. Despite Burnside appearing in the show until early 2000, Henderson was not seen again. Senior Crown Prosecutor Matt Hinckley was a semi-regular character featured in the show between 2006 and 2007, played by Mark Dexter. The character first appeared in "The Green Eyed Monster" (Episode #410) and made his last appearance in "Day of Reckoning". Hinckley is introduced as the long-term boyfriend and fiancée of PC Emma Keane, as well as the station's new regular duty solicitor, in "The Green Eyed Monster" (Episode 410). Emma informs her colleagues that she and Matt have been dating for two years prior to his appointment at Sun Hill. Shortly after accepting his new post, Emma breaks off their relationship after she drunkenly snogs Will Fletcher. Unaware of her betrayal, Matt tries to make it up to her and presents her with a bouquet of flowers. However, Matt catches Emma giving Lewis Hardy a peck on the cheek and suspects that they have been having an affair. When Matt confronts Lewis, Will steps in and claims that it was him whom Emma kissed, unaware that Matt wasn't aware of the incident between them. Matt attempts to punch Will but misses, but Will retaliates with a punch in the face. Matt subsequently brings charges against Will for assault, but subsequently drops them after believing that Emma will get back together with him. Some months later, he and Emma have reconciled their relationship and have agreed to marry. However, the night before the wedding, Emma opens up to Matt, and tells him that she had another brief affair with Will during their engagement.
