In 1991, Miguel Angel Martinez,17, Manuel “Milo” Flores,17, and Miguel Angel Venegas, Jr.,16, each played a role in a triple axe-and-knife murder that rocked the small city of Laredo, Texas.

Drunk and high on cocaine and marijuana, the young men invaded the residence of 33-year-old James Smiley, 33, a Baptist youth counselor. Having a previously established relationship with Smiley from working under him at an Arby’s restaurant, Martinez had a house key that got the group access.

Some of the facts surrounding the murders are unambiguous: Venegas used the axe to kill Ruben Martinez, 20 years old, who was sleeping on a couch. Miguel Martinez also stabbed that victim with a folding knife. Then Venegas went into two other rooms of the house, killing Smiley and 14-year-old Daniel Duenez. Martinez and Venegas then stole a television set, a telephone and Smiley’s car.

Martinez was immediately tried as an adult, convicted of capital murder, and sentenced to death. That made him the youngest person on Texas’s death row, drawing international attention. In 2002, his sentence was commuted to life imprisonment.

The motivation behind the seemingly random explosive violence remains shrouded in mystery. But Martinez, Venegas and other community members give their versions of the night in question in a series of straight-to-camera interviews on Episode 4 of “I Am a Killer,” available on Netflix.
