Motive for Florida family’s massacre may never be known

"Someone pounded on Miguel Rivera’s sliding glass door early Sunday, but when he went to investigate, no one was there. Minutes later, gunfire erupted at his neighbor’s house, where authorities say a Marine vet who thought he heard the voice of God killed four people, including a 3-month-old boy.

Rivera said he believes Bryan Riley might have killed him if he had gotten to the door sooner.

“I pray to God every day I am alive still,” Rivera said Tuesday from the front porch of his Lakeland home. “I feel sad for those people. God rest their soul.”

Riley, 33, is being held without bond on four counts of first-degree murder for the slayings of Justice Gleason, 40; his 33-year-old girlfriend, Theresa Lanham; their son, Jody, who was born in May; and Lanham’s 62-year-old mother, Catherine Delgado, who owned the property. He is also accused of seriously wounding an 11-year-old girl and killing the family’s dog."
