A man who admitted neglecting his four-month-old son who died when the boy's mother knocked a television onto him, has been jailed for 46 months.
Kian McMillan suffered a brain injury in the incident at the house in Burnley in December 2011 and died the next day.
His father Edward Hanratty, 41, of Dirkhill Road, Bradford, admitted child neglect but failed to appear at Preston Crown Court for sentencing in January.
He was arrested in West Yorkshire last month and jailed at Preston.
Hanratty received a 10 month term for Kian's death and three years for conning a 91-year-old man from Bradford out of his life savings.
Kian's mother Natalie McMillan, 25, of Clarendon Road, Leeds, was cleared of manslaughter but admitted child neglect at an earlier hearing.
She was jailed for 15 months on 31 January.
The child died from head injuries he suffered as he lay on a changing mat at the family home when his mother, who had been taking drugs and drinking alcohol, tried to plug in a scart lead to watch a DVD.
While this was happening Hanratty had passed out on the kitchen floor due to drugs and drink.
The Recorder of Preston, Judge Anthony Russell QC, told Hanratty,: "It was abundantly clear that you and your partner were in no fit state to look after your child that night.
"Over the short life of your child you gave priority to yourself and your self-indulgent drugs lifestyle and neglected the life of Kian.
"You must bear some responsibility for the death because you were the father of Kian. You failed lamentably. You should have protected Kian from his mother's neglect."
Hanratty had failed to turn up for the sentencing in January at Preston Crown Court because he said he had no money for his train fare from Bradford.
He was later arrested and remanded in custody where he was also sentenced to an additional three years in prison after he admitted conning a 91-year-old man from Bradford out of his life savings.
Hanratty drained nearly £30,000 from his victim to feed his drug addiction, the court heard.
He had befriended the pensioner some 15 years earlier when randomly knocking on his door and asking for financial help.
They became friends but as the years went by Hanratty became more persistent in asking for money.
