Relatives found the 26-year-old man dead early Wednesday morning inside a home on Ruthann Drive in southeast Fort Worth.
Police said he died from a gunshot wound that did not appear to be self-inflected.
Officers processed the scene and interviewed family and friends. They're still trying to figure out what happened.
No arrests have been made and no suspect descriptions have been released.
Friends said the victim was a nice guy and they don't know why anyone would want to hurt him.
He was reportedly a father of two with another baby on the way.
