A Lubbock County jury has sentenced a man to 18 years in prison for the fatal beating of his cousin as the men argued about their wives - who are sisters. 

Jurors on Wednesday convicted 24 year old Danny Ray Martinez of murder in a December fight that led to 34-year-old Eddie Moreno's death. 

A police report says Moreno suffered head trauma during the fight with the defendant after both had been drinking.  The fight between the men started because Moreno was upset with his wife and attacked her then cursed out Martinez's wife for trying to check on her sister.
