Murder Story

On March 30, 1985, Mariano Juarez Rosales committed a series of murders in Harris County, Texas. In the early morning, after a night of heavy drinking, Rosales sought out his estranged wife, Mary, who was with another man named Hector Balboa.

Rosales called Hector's home to obtain the address. Once he had the directions, he went to the house with a pistol. Without warning, he entered and found Pete Rodriguez, who was watching television. Rosales shot Pete point blank in the head, killing him instantly. He then turned the weapon on Patricia Balboa, Hector's sister, shooting her twice as well.

Afterward, Rosales moved to the back of the house where 15-year-old Rachel Balboa was asleep. He shot her twice, causing fatal injuries. Next, he approached Hector’s room and fired shots through the door, hitting Hector. A struggle ensued, resulting in both men being shot.

Hector managed to escape outside, and Rosales chased him while still pointing his gun. He pulled the trigger multiple times but the gun had run out of ammunition. After the shootings, Rosales got into his truck and left the scene. Two of the victims survived, but Pete Rodriguez and Rachel Balboa did not.

Mariano Juarez Rosales was later arrested and sentenced to death on December 27, 1985.
