Police said Frederick Torremocha, who was reeking with liquor, went to the house of 17-year-old Lyka Umali to court her.
But Umali turned him down. Slighted, Torremocha grabbed a kitchen knife and stabbed her. She also attacked her aunt, Rebecca, and grandma, Belen, 71.
Lyka and Belen were killed on the spot, while Rebecca died in the hospital the next day.
Torremocha tried to escape, but lawmen cornered him in a grassy area. Before he could be arrested, he shot himself with a homemade caliber .22 pistol. He died hours later in the hospital. Arnell Ozaeta
