Nineteen-month-old Mia was the daughter of Merrick McKoy, 22, and Kimphone 'Kim' Phanthavongsa, 21, who had recently broken up.
Kimphone called police at 9:35 a.m. Monday morning, reporting that Merrick was inside her apartment with their infant daughter and a handgun.
Before the incident, Merrick posted several ominous updates on his Facebook account.
It is being assumed that this was addressed to Mia's mother, Kimphone.
He also posted this selfie with Mia.
This was the final update Merrick posted:
Family members told Denver's ABC News 7 that Mia was unconscious when paramedics rushed her to the hospital where she was later pronounced dead.
Merrick was taken to a different hospital and authorities have yet to release his condition.
As seen here, the top of Merrick's Facebook profile says "fuc kim."
