A West Yorkshire jury found Polish native Marcin Kasprzak, 25...guilty of attempted murder of his partner.
He stun gunned his finance...Michelina Lewandowska...and buried her in a cardboard box.
She used her engagement ring to cut the box apart...and dig out.
Lewandowska recalled :“During my time inside my shallow grave where I was buried alive, I feared that my life was at an end and I was going to die.
"I prayed to God to help me to survive so that I could look after my young son. The thought of my son gave me the strength to fight my way out of the box and save myself."
