Sadly, Sam Johnson, 25, of Jarrow died on Sunday evening.
His family have paid a heartfelt tribute to Sam and say he will leave ‘a huge hole in everyone’s lives’.
In a statement, they said: “Sam was aged 25 and a much-loved son of Christine and Carl.

"We will continue to offer Sam’s family any support they need and would ask everyone respects their privacy as they attempt to come to terms with what has happened.
“We are determined to finding out what happened in the moments immediately before this collision, and would continue to ask any witnesses – or anybody with information that they think could assist our investigation – to get in touch.
