SHREVEPORT (AP) — The investigation continues but no arrests have been reported so far in the triple-killing that stunned Shreveport’s Mooretown community late last week.

Authorities spent the weekend trying to figure out who killed 78-year-old Irene Ellison; her daughter, 41-year-old Carise Ellison; and the daughter’s boyfriend, 58-year-old Brian Wilson. The three were found stabbed to death Thursday inside of their residence.

The Times reported that the victims were found in separate rooms. Police say there were no signs of forced entry.
