Richard Bliss was described by his family as “generous, kind and thoughtful” after he died last week.
The 19-year-old’s body was spotted by a passerby in the River Mersey at 4.55am last Sunday.
Paramedics attempted to revive him but he was pronounced dead in hospital.
It emerged Richard sent a text to his mum Yvonne saying “I love you”– to which she responded “I love you too”.
He then didn’t reply, and the following morning he was found dead – with his parents got a knock on the door at 6.30am.
“He sent his mum a text saying ‘I love you’ ”
Richard’s dad Keith
His dad Keith, 52, from Bootle, told Liverpool Echo that the day before his son’s death he had dropped him off at the Marks and Spencer’s where he worked in Aintree Retail Park.
The dad-of-six said he had a “normal conversation” with his son, chatting about football and making plans for the future.
Richard had been a big Liverpool fan – despite his dad supporting Everton – and was making plans to watch last night’s opening game against Norwich.
“He was making plans, speaking about the future. And we just had a normal conversation, I had no idea that it would be our last,” he said.
Keith revealed his son had arranged to go out with some pals from work – and left the house at around 10pm.
Something had happened that night which made Richard upset, with his dad saying pals rang the police after he “ran off after a disagreement”.
“He sent his mum a text saying ‘I love you’ and she woke up in the middle of the night and responded ‘I love you too’ and she didn’t think anything of it,” Keith said.
“Obviously he didn’t reply to that message.”
Keith, who works as a civil servant said “there were no clues” that his son had been upset before the night out.
“He had obviously been drinking heavily and had got upset, but that is not unusual for someone of his age and is typical student behaviour and just part of growing up.
“But you would usually just wake up the next day with a hangover and it be forgotten.”
He added: “I don’t know if he had had something on his mind and after having alcohol it had pushed him over the edge.”
Keith, who is separated from Richard’s mum, said the whole family are distraught – including his three brothers and two sisters – one of whom turned nine the day after her big brother’s death.
The devastated dad said: “He was a model pupil at school, a lovely, gentle natured boy.
“Every parents evening the teachers would say to us ‘I wish we could have a class of Richards’.
“He was generous, kind, very intelligent and always thought of others and always had others’ best interests at heart.
“I never heard him say a bad word against anyone – that was just his character.”
