Enhancement and transcription in a murder case |

In this trial for murder, we were asked to enhance sections of audio from a mobile phone video which had been taken while the suspects were burning articles of clothing worn during the murder of Barry Smith.  The enhancement and transcription provided key evidence of the suspects’ involvement in the incident. Vincent Aitken will serve a minimum of 22 years while Nathan Doherty was sentenced to a minimum of 18 years. Emma Aitken will serve a minimum of 12 years.
