Rather than deal with the fact that his girlfriend didn't want to get back together with him, Benton County prosecutors say that Gustavo David Martinez Aquepucho killed her and their baby boy by slitting their throats with a knife. Now the Oregon State University student is facing a possible death sentence if he's convicted of the three aggravated murder charges he now faces.
Martinez is charged with three counts of aggravated murder for the stabbing deaths of Kelsey Rozetta Baker, 19, and their son, 1-year-old Theo Martinez. Baker and her child were killed Friday at a residence where the three had lived together, 24882 Evergreen Road near Philomath.
Documents filed in connection with the case Monday charged that Martinez decided to kill Baker and the toddler after Baker told him that she would not reconcile with him. An affidavit filed in the case alleged that Martinez then planned to kill himself so the family could be together in the afterlife. (See the related story.)
Aquepucho, a Peruvian native who moved to the United States in 2007 to study abroad in high school, then stayed to continue at OSU, had moved in with the family of Russell Anderson, Ann Marchant and Rozetta Baker in Philomath, Ore.
He and Baker soon started dating, and after high school they continued their relationship as OSU students. A year ago that relationship became more serious when their 1-year-old son Theo was born.
But things soon soured and supposedly Baker broke off the relationship with Aquepucho.
This was too much for the 20-year-old and instead of moving on he allegedly drugged Baker with over-the-counter medication then slashed her throat with a knife.
Next he supposedly put duct tape over the mouth of his young son to keep him quiet and dragged the same knife along his throat.
Aquepucho is currently being held in Benton County Jail.
Prosecutors have not yet said whether they will seek the death penalty.
