Police rushed to the apartment complex and found the boy with a gunshot wound to his chest or upper arm area. He was taken to Memorial Hermann Greater Heights Hospital, where he died from his injuries.
"There was some kind of interaction where they had a gun," Houston police Lieutenant Larry Crowson said. "It doesn't appear intentional. It appears to be a tragic accident."
Investigators are trying to figure out who owns the gun and how the boy's cousin got his hands on the weapon.
The Harris County District Attorney's office will decide whether an adult should be charged.
Children under the age of 10 cannot be held criminally responsible, police said.
