In a case where 13 arrests were made and the murder weapon was recovered, it would have been reasonable to hope that justice would follow soon after.
But almost eight years on, no-one has been charged over the murder of 17-year-old Kevin Wilson, a Scotland native who moved to Liverpool and it is believed fell in with a bad crowd.
Detectives at the time believed Kevin had been lured to the junction of Smithdown Road and Holmes Street in Wavertree at around 8.30pm on February 7, 2015. What interaction took place, if any, between Kevin and his killers is not known, but it ended with a single bullet from a 9mm Russian Baikal automatic pistol striking the teenager in the back.
