A mobile DNA laboratory in Izyum, eastern Ukraine, was set up this week to help relatives identify the bodies.
Around 50 people came on Friday in the DNA sampling organised in a parking lot in Izyum, reports AFP.
“I am searching for my father, Anatoly Matyshko. His neighbours say he was killed on March 10 by shrapnel and buried in his garden,” Ms Inna Kupriyanova.
"He was unearthed and taken to the Kharkiv morgue, but another body was found in the same garden."
"So I am coming to give my DNA, so that we can really identify my dad and give him a proper burial," the 46-year-old nurse explained.
People had to go through the painful procedure of going to the morgue to identify the dead before the mobile lab set up.
The mobile lab`s manager, Viktoriya Bulavina said, that, DNA sampling "helps us to identify the exhumed corpses, because they were there for more than a day... the relatives are often not able to identify them,"
Since the area was liberated in September, 750 bodies have reportedly been exhumed from various burial grounds, according to the regional prosecutor.
