Kim Kardashian's support is going a long way for Texas death row inmate Melissa Lucio, who has newfound hope ... despite her looming execution date.
We caught up with Melissa's son, John Lucio, who was heading to a rally in Dallas to protest the impending execution.
John tells TMZ ... when he told his mom Kim Kardashian was advocating on her behalf, she was shocked and couldn't believe it. He says, Kim supporting her, alongside many others, really uplifted her spirit.
Kim has called on Texas Gov. Abbott to halt the execution ... which is scheduled for April 27. She's spoken out on this issue on her social media and shared a letter to the Governor from Melissa's 14 children.
Melissa has been sitting on death row for nearly 15 years. She was convicted back in 2008 of murdering her 2-year-old daughter. Melissa told cops her daughter fell down a flight of stairs when they arrived.
