BALTIMORE, Md. (WBAL/CNN Newsource) - A Baltimore-area man was beaten to death outside his home Friday evening. His fiancée said he died protecting her son from a fight that came to their doorstep.  

Christopher Wright, 43, was killed protecting his kids from a fight that started at Brooklyn Park Middle School and was brought to his home in Ann Arundel County. 

"So then Chris came out and tell them like 'he's not coming out here to fight' and they had threatened at one point to come in and get him, said Tracy Karopchinsky, Chris' fiancée. "And then they said that if you're not, if he's not going to fight, then you're going to fight us."

Tracy said three teens and two adults showed up looking to fight her 14-year-old son. But what happened next was criminal. 

"Just looking at the damage that was done to him," Tracy said, "that was not, it wasn't, that wasn't just punching that did that. Like, there's no way that that was just punching that did that. I mean, the damage was done before the ambulance ever took him away. He had had a seizure, it was done. There was nothing that the hospital could do."

Wright was taken to the hospital Friday and was pronounced dead Saturday from a traumatic brain injury. The incident was caught on the victim's and neighbor's security cameras. 

"And the first video that comes up is my 12-year-old son screaming, 'Daddy, daddy, daddy' and running out of the house to go into the street and help his dad and I couldn't watch anymore after that. I just couldn't."

School officials confirmed the fight between the teens and said they worked to address the issue. Now they're working with police on the investigation.

"Anybody who assisted or abetted or was an accomplice of the main suspect or the primary suspect in this incident would be culpable," police spokesperson Marc Limansky said. 

Tracy said Chris was a devoted father who loved the stars and gardening. Her best friend was taken over senseless violence. 

"They didn't just ruin our lives. Their lives are gonna be changed forever," Tracy said. "Their parents' lives are gonna be changed forever, and nobody thinks about that just from a fight. It's everywhere. Tt is everywhere and somewhere we as parents are failing these children, like as parents, we are failing. It's not the school's responsibility, it's our responsibility.
