A jury in Fort Worth on Thursday sentenced 29-year-old Roberto Sanchez after convicting him of murder.
Authorities say Sanchez fatally stabbed 30-year-old Sergio Gonzalez outside a Fort Worth bar. Officials believe the men were arguing about a woman who is a cousin to Sanchez.
The Fort Worth Star-Telegram reports Gonzalez had known the woman for two years and she was with him before deciding to leave the club with Sanchez.
A confrontation broke out between the men. Witnesses say Sanchez later bragged about the killing.
