Prosecutors say teenager killed mother and showed friend's body: 'Are you squeamish?'

According to prosecutors, a friend who desperately sent a message to her friend one afternoon last March asking her to come over and help her with an “emergency” had no idea what she would experience next.

“Are you squeamish around dead bodies?” 14-year-old Carly Gregg allegedly asked her friend as she opened the front door, according to Mississippi District Attorney Kathryn White Newman in footage aired by CourtTV of her statements in the murder trial of the now 15-year-old. Local stations WAPT and WJTV also reported on Newman's opening statements in the trial, which began Monday.

According to Newman, moments later Gregg led her friend into her bedroom where her mother lay dead on the floor from three gunshots, CourtTV and WAPT reported. Newman said in the courtroom that Gregg's mother searched her daughter's bedroom for vape pens, WLBT also reported.

Gregg is charged with murder and attempted murder, according to The Clarion Ledger, WLBT and WJTV, Prosecutors allege that the young girl shot them with her mother's gun in the family home in Brandon, Mississippi, and then called her friend into the house.

The teenager is later accused by prosecutors of setting up an apparent ambush to shoot her stepfather, Heath Smylie, when he returns home, WLBT, WJTV and The Clarion Ledger reported.

Newman presented the prosecution's case to jurors on Monday, according to a courtroom video shared by Court TV. Newman claimed the teenager came home with her mother, a math teacher at Northwest Rankin High School, where Gregg was a student. Gregg went straight to her parents' bedroom to retrieve a .357 Magnum pistol from under her mattress, Newman claimed. Gregg hid the gun behind her back, went into her own bedroom and confronted her mother, shooting her three times, Newman said, according to The Clarion Ledger, WLBT and WJTV.

At a preliminary hearing in April, recorded and published by the blog Jackson Jambalaya, Rankin County Investigator Zachary Cotton said there was surveillance camera footage showing Gregg's allegedly indifferent behavior before and after the shooting.

Cotton claimed that a video showed the teenager returning to the kitchen after killing her mother, where the suspect could be seen texting from a phone. The investigation revealed that the teenager sent a message to her stepfather asking when he would be home, Cotton said.

Cotton claimed in court that between killing her mother and attempting to shoot her stepfather, Gregg was seen in another video “singing to her dog” before texting her friend to come to the house.

When her stepfather returned home, prosecutors said Gregg tried to shoot him and then fled through the family's backyard after a scuffle over the gun, WJTV, WLBT and CourtTV reported.

She was arrested shortly thereafter near the house, WAPT, WLBT and WJTV reported.

Gregg faces two life sentences if convicted of murder and attempted murder, according to The Clarion Ledger, WAPT and CourtTV. The stations report that the teenager rejected the state's plea deal, which called for a 40-year prison sentence, and that her defense attorney pleaded insanity.
