According to police, the brawling had been ongoing for days as two women in their 40s were involved with the same man.
Now, 44-year-old Raquelle Casillas is in the St. Clair County Jail charged with open murder for killing the 44-year-old Almont woman she identified as her best friend in a Facebook post.
Three days ago, Casillas posted a photo to her Facebook account, which showed both women with black eyes, cuts, and bruises smiling.
She captioned it by saying they were best friends. A day later, at 4 a.m., the man at the center of the love triangle called 911 from his home on South Main Street in Capac because that 44-year-old Almont woman was unconscious and could not be revived.
She was taken to McLaren Lapeer and diagnosed with severe head trauma and later died.
Neighbors told Local 4 seeing police at the home was not uncommon.
