Well-known MMA fighter Marcus Kowal is grieving with his family after the tragic death of his infant son.

The toddler was being pushed in his pram when a drunk driver hit him near his home in California. Kowal took to Facebook yesterday to share his thanks to those who have offered their support. “I want to thank everyone who has been there for us, in all forms and shapes. Thoughts, prayers, in person – whatever. We’ve received 100s and 100s of txt messages, emails, fb messages, etc – we are blown away. Your support means the world to us,” he wrote. He explained that his son was declared brain dead only an hour earlier. “He tried to fight so hard. He even died at one point but they brought him back. He’s a little fighter. His heart is still beating but his brain is no longer working. Our hearts are broken and there’s a void in my soul but we will get through this. Again, your support means the world and I wish we could respond to each and every one of you but right now, we are going work through this. Funeral arrangements will be posted here. Thank you. RIP Liam Mikael Kowal,” wrote the heartbroken father. In a post today the fighter announced that the family had made the decision to donate young Liam’s organs. Taking to Facebook Kowal shared the news: “This isn't easy to write but Liam is going to donate his organs, so that his little heart can make another child live and another set of parents not have to go through what we have to. We were told that we can donate to someone we know. Therefore, I am writing this post to ask if there is a child out there we know that needs a heart or any other organ.” Our thoughts are with the Kowal family at this time. A GoFund Me page has been established by friends to help with funeral costs, medical expenses and to begin forming a memorial fund. Details can be found HERE.
