But that's what police say happened Wednesday night at the Oak Meadows apartment complex in Shreveport.
"There were three brothers involved. Two of the brothers were talking. One of the brothers came around and accosted the suspect. Before it was said and done, the suspect had stabbed the victim twice," Frazier said.
According to police the fight started outside in a courtyard. After the stabbing the victim went inside an apartment building. He came to the first door inside and knocked on it. The woman inside the apartment called 911.
"The fire department had to put a chest tube in so it's a serious injury; a very serious injury," added Frazier.
The victim is 16-years-old. He was taken to LSU Medical Center. His older brother is accused of stabbing him. According to police, he left the scene after the fight and is still at-large.
The three brothers involved in the fight don't live at the Oak Meadows apartment complex. It's a gated community, so police aren't sure why they were there. Police say despite the gate, trespassing is a problem.
"This apartment complex; it's an ongoing issue that we're trying to address,” said Frazier.
Police are waiting to determine what kind of charges will be filled against the brother. If the 16-year-old dies, he could face murder charges.
