KANSAS CITY, Kan. -- KCK police now say the triple homicide and house fire Monday 'originated from a previous dating relationship.'
Police arrested 31-year-old Ismael Caballero Monday and are holding him on first-degree murder.
At this point, prosecutors have not yet charged Caballero.
The three victims were discovered when crews responded to a house fire early Monday at a home on Mill Street near Central Avenue around 4:30 a.m.
But it wasn't the house fire that killed them, officials said.
Police confirm the victims are 31-year-old Yazmin Rodriguez, along with her 14-year-old daughter Amerikha and her 10-year-old son Jeancarlos.
KCK police said charges are pending, based on review by the Wyandotte County District Attorney's Office.
There is a Go Fund Me page set up to help the family.
