Two brothers charged with murder appeared in court today along with their mum, who is accused of disposing of evidence.
Michael Rainsford, 20, was shot through a kitchen window in front of his family at their home in Harrington Road, Litherland.
Police said they were called to the scene following reports a man was shot through the window of a house by offenders believed to be on an electric bike.
The Hugh Baird student was standing next to his dad moments before he was hit in the chest and back, at around 11.10pm, on Tuesday, April 4 this year.
He fled into a hallway to escape the gunman but collapsed and, despite the efforts of his dad, Michael Rainsford senior, and brother Joshua Rainsford, 16, later died.
Michael Foy, 22, and James Foy, 18, both of Rossini Street, Seaforth, appeared in the dock at Liverpool Crown Court charged with Mr Rainsford's murder.
They are also both charged with possessing ammunition for a firearm without a certificate and possessing a firearm while committing an offence, "namely murder".
The brothers' mum, Joyce Smith, 45, her brother and their uncle Craig Johnson, 38, and Smith's neighbour Andrea Saunderson, 47, are charged with perverting the course of justice in relation to the case.
According to the charges against Smith and Saunderson, they "with intent to pervert the course of public justice, did a series of acts, namely, the removal/disposal of evidence which had a tendency to pervert the course of public justice".
It is alleged that Johnson perverted the course of justice "by storing an electric bike in his shed then facilitating its removal knowing or suspecting it would be relevant to an ongoing criminal investigation".
Michael Foy, with short brown hair and wearing a grey zip-up top, and his younger brother James Foy, with long brown hair and wearing a grey sweatshirt, spoke only to confirm their personal details.
Simon Driver, prosecuting, said a provisional murder trial would be estimated to last four to six weeks.
Judge David Aubrey, QC, fixed this trial for January 11 next year.
Smith, also of Rossini Street, with brown hair tied up in a bun and wearing a grey sweatshirt, next appeared in the dock alongside Saunderson, of Keston Crescent, Stockport, with her black hair tied up in a bun and wearing a white coat.

Johnson, of Willard Drive, Bootle, with short grey hair and wearing a black sweatshirt and blue jeans, was allowed to sit at a bench in front of the dock.
They spoke only to confirm their details and were told they would next appear alongside the Foy brothers at a plea and trial preparation hearing on August 17.
Matthew Buckland, defending the Foy brothers, did not make any application for bail on their behalf.
The judge remanded them both in custody but granted their mum, uncle and Saunderson conditional bail.
Smith, Johnson and Saunderson's bail conditions include a requirement not to contact any prosecution witnesses and a condition of residence.
Speaking to the ECHO after his son's death, Mr Rainsford said his family were "devastated and heartbroken".
The grieving dad said: "He was a lovely young lad, who loved his friends and family, who loved him too.
"He wasn't a lovable rogue - he was a normal young man.
"We are only a small family and can't comprehend why such a thing has happened."
Police said an 18-year-old man, from Netherton, was also arrested on suspicion of conspiracy to commit murder earlier this week, but released under investigation.
That followed the arrest of five people on suspicion of murder in July, who were also released on bail, pending further investigation.
