A Maryland father died Saturday after sustaining life-ending injuries while defending his children after a schoolyard fight took a dark turn. 

Christopher Michael Wright, 43, met two adults and three teens who approached his home on May 19 around 5 p.m. and assaulted him when Wright refused to let them speak with his fiancée’s son. 

The boy, 14, had gotten in a fight at Brooklyn Park Middle School with another teen, and they wanted to continue the fight after school, but Wright told them he was not going to let them fight with the boy. His fiancée, Tracy Karopchinsky, told 11 News that the suspects had then turned their attention on Wright, telling him that if the boy would not fight, they would fight with him instead. 

Anne Arundel County Police responded to calls of an assault and arrived on the scene shortly after 5 p.m. to find Wright already receiving treatment from county fire department personnel. Responders then rushed Wright to a local trauma center for treatment as his injuries were life-threatening.

Wright succumbed to his injuries and died around 9:45 p.m. Saturday and was pronounced dead at the hospital. 11 News reported his cause of death as traumatic brain injury. 

Police have said they are treating the incident as a homicide and have asked anyone with information to contact them. Police listed the suspects as three to four White males in their mid-20s to mid-30s in age. Anne Arundel County Police said there have been no updates to the case and no arrests made as of Wednesday, May 24.

"Anyone who assisted who abetted or was an accomplice of the main suspect or the primary suspect will be culpable," Anne Arundel County Police spokesman Marc Limansky told local news of the investigation. 

The school confirmed the fight to 11 News, and Karopchinsky told the outlet about how her 12-year-old had tried to run out into the street to help Wright, but it was "too late."

"Just looking at the damage, that wasn’t just punching that did that," Karopchinsky said. "Like, there’s no way that punching did that. The damage was done before the ambulance ever took him away."

"He’d had a seizure. It was done," she added. "There was nothing the hospital could do." 

A missing 4-year-old boy who was swept away with his 8-year-old sister in a raging California river over the weekend was found dead Monday, a day after searchers recovered the girl’s body, authorities said.

Rescue personnel spotted the boy beneath the water against a tree in the Kings River, about 1.75 miles from where he and his sister initially entered the turbulent water on Sunday, the Fresno County Sheriff’s Office said. 

The search for the siblings began around 2 p.m. Sunday after the pair fell into the cold river and were swept downstream, officials said.

The children had entered the water with their mother and her adult friend about a mile down from Pine Flat Dam while trying to climb onto a specific rock, according to the sheriff’s office.

Neither child was wearing a life jacket.

Deputies and Cal Fire firefighters responded with rescue boats and launched a search.

Less than an hour later, the 8-year-old girl was found dead about .2 miles from where the current carried her away. Her brother, however, remained missing.

On Monday morning, about 40 rescue personnel continued the search for the missing boy using boats, a remote-controlled vehicle in the water, drones and a helicopter.

No additional information about the children’s deaths was immediately released.

Both the Kings and San Joaquin rivers have been closed to recreational users since March.

Authorities warned that "heavy winter storms and melting snow … have created high water levels and hazardous conditions."

"The water remains cold, in the low 50s, the current is swift and trees serve as dangerous obstacles," the sheriff’s office said.

The rivers will remain closed until the "extraordinary dangerous conditions" improve, officials said.
