Stepdaughter, 19, 'shoots dead her pregnant stepmom, 36, just days before her planned C-section and tries to strangle the victim's 11-year-old son'

• Passion Watkins, 19, from Georgia, charged with malice murder, aggravated assault, cruelty to children and feticide
• Accused of shooting dead her step-mother, Melanie Powers, three days before she was due to undergo C-section and welcome her baby daughter 
• Watkins is also charged with attempting to strangle her step-brother, 11 

Authorities in Georgia have arrested a 19-year-old girl who was accused of shooting dead her pregnant stepmother and attacking her 11-year-old stepbrother on Sunday. 

Deputies from the Bibb County Sheriff’s Office were sent to a home in the 1000 block of Radio Drive just before 6.40am and found 36-year-old Melanie Powers in bed dead from a gunshot wound to the head. 

It was reported that Powers’ 11-year-old son ran from the home to get help after he was awakened by his step-sister, Passion Watkins, assaulting him and his mother.

Watkins was arrested in a park in Macon, Georgia, on Sunday night, hours after the killing 

After following up on leads, deputies tracked down Watkins sitting in a park on Pansy Avenue just before 6pm. 

Following an interview with investigators, the 19-year-old was booked into the county jail on charges of malice murder, aggravated assault, cruelty to children and feticide, stemming from the death of Powers' unborn daughter. 

The victim's son was taken to a hospital to be treated for non life-threatening injuries. He was later released into the custody of family members. 

A friend of Powers with a purported knowledge of the incident described Watkins in a Facebook post as 'the face of evil,' saying that she murdered 'an amazing person' who took her into her home to save her from her abusive father, and who loved the girl as if she were her own child.

Melanie Leigh Bongiorno also revealed in the status update that Powers was due to undergo a scheduled Cesarean section within three days week and welcome her baby daughter. 

Bibb County Coroner Leon Jones has corroborated that information, telling 41NBC that Powers was eight-months pregnant and scheduled for a C-section this week.  

According to Bongiorno, Watkins shot her step-mother from a point-blank range and attempted to strangle her 11-year-old step-brother, who had lost his biological father to diabetes six years prior.

'I hope Passion Watkins from Macon, Ga gets the death penalty for what she did!' Bongiorno wrote. 'This is horrible, and the worst kind of evil there is!!'
