A police officer in Florida has died almost three years after being left in a coma from a gunshot to the face while responding to a domestic violence call in which the suspect killed four children before taking his own life.

Orlando Police Officer Kevin Valencia died on Monday, Police Chief Orlando Rolon said in a statement.

“Officer Valencia risked his life for people he didn’t even know — a risk that many in the law enforcement profession take without question,” Rolon said. “Since that tragic night, Officer Valencia has been fighting for his life with his family by his side.”

According to reports, Valencia attempted to kick down the door to the victims apartment in June 2018. Valencia had a daylong standoff with the suspect.

When officers finally entered the apartment, they found the children dead and the suspect dead from a self-inflicted gunshot wound.
