It's day one of a murder trial at Glasgow high Court. Three people stand accused of the 1996 murder of Caroline Glachan, and as the trial begins, a jury starts to learn some of the facts about the case. First to give evidence is Caroline's mother Margaret, who casts her mind back to the last time she saw her daughter, and the tragic circumstances which led her to find out she had been killed. Also taking the stand - a police diver who recovered Caroline's body from the River Leven, and a witness who reveals that the murder was the only topic of conversation in the area in the days afterwards. Defending Advocate Tommy Ross KC joins journalist Jane MacSorley as they listen to the evidence and break down the tactics as this extraordinary trial gets under way.

For 25-years, Caroline Glachan's family had no answers on why she died, or who killed her. Her body was found face down in the River Leven. The 14-year-old schoolgirl had been battered, and left for dead. Now - three people stand accused of the crime. Prosecutors believe they acted together, to kill Caroline. But the trio deny any involvement. This series features unique recordings from inside the court room. And it features expert analysis from Tommy Ross KC - one of the defence advocates in this trial. Each episode tells the story of one day in court. By the end, you'll hear what the jury heard. But when it comes to reaching a verdict, what will they decide? What would YOU decide? Season 2 of Inside Murder Trial launches on November 27th. Listen to all episodes first on BBC Sounds.

We hear the closing speeches. Lord Armstrong invites the jury to retire and begin their deliberations. Will they find William MacDowell guilty of murdering his lover and their son?

Defence witness, Dr Gamblin, who was Renee’s GP gives evidence about an encounter outside his practice that has haunted him for over 40 years.

Fresh evidence is presented surrounding a clandestine meeting months before Renee and Andrew disappeared. There is an offer of money for a job that needs doing.

We hear from the accused, 80 year old William MacDowell, about his illicit affair with Renee and how he regularly treated her.

Five days after Renee and her son Andrew vanish, the accused makes a most unusual and urgent request for his company car which he is forced to return having being sacked.

For 46 years Rosemary MacDowell has stood firmly by the accused, her husband. Today she takes the stand giving her version of the night when her husband's lover disappeared.
