Fiancée's callous response to cops after learning her partner's mistress had died of her injuries after beating her up on camera while her cackling accomplice filmed

Grim police footage has laid bare the moment a scorned fiancée realizes she faces years in jail after beating up her partner's lover and leaving her for dead.

Antonetta Stevens, 27, pretended to be her partner to lure his lover Ashley Bocanegra to their home in Burford, Georgia, with a text message from his phone.

In the newly-released footage filmed by her cackling partner's sister Janine, Stevens stormed over to the mother-of-one as she arrived, grabbing her hair, forcing her to the ground and launching a flurry of blows against the 30-year-old.

Bocanegra took herself to hospital where she later died from internal bleeding. Police later arrived at the home to inform Stevens about the fatal consequences of her jealousy.

Upon learning Bocanegra had died as a result of her injuries, she callously responded to cops: 'Okay, um wow I'm so sorry about that, um, that was not my intention.'

'I've been mentally going through a lot,' she bleats. 'I have bipolar depression and I'm just going through a lot right now.'

Bocanegra, 30, was the married mother to a seven-year-old son and died as a result of her injuries after the brutal attack 

The killing in August 2022 made headlines across the country but the extensive police interview footage has just been published by Law & Crime.

Both women are now in Arrendale State Prison serving 20-year sentences for voluntary manslaughter and robbery by force.

The drama began after Stevens found out her partner of five years and father of her three-year-old son, Daniel Gonzalez, was having an affair. 

Bocanegra was his manager at a nearby Floor and Decor depot, and Gonzalez had confided with his 17-year-old sister Janine about his tryst.

Janine told Stevens who hatched her revenge plot after seeing her partner and his lover walking together near the store on his lunchbreak.

The following day she marched up to Bocanegra as she approached the apartment block in response to the bogus text message.

Janine was following right behind filming the encounter on her phone as Stevens approached her victim shouting 'I will murder you'.

'I will do worse to you,' she screams as she punches Bocanegra in the face.

'That's why he was trying to protect you, but now he don't care for you to get your a** beat.'

Janine dragged the helpless victim along the street, pulling her hair, as Stevens rained lethal blows down on the woman.

The pair grabbed her phone, intending to use it to inform Bocanegra's husband about her affair and left her sitting battered and bloodied in the street as they returned to the apartment.

She was left battered and bloodied in the street from the furious assault before dying from her injuries in hospital later that night 

Stevens, left, was incensed when she discovered that partner Daniel Gonzalez was having an affair with his slightly-built co-worker. She's seen here when officers made their first visit to the home after the incident was reported to police before the full extend of Bocanegra's injuries were known 

Gonzalez had been obliviously asleep while the attack took place and awoke to the sound of his lover knocking at the door asking for her phone back.

Her attackers handed it back and she had limped away before police arrived in response to neighbors' 911 calls.

They were back again that evening after their victim, who was mother to a seven-year-old son, deteriorated in hospital to inform the pair that the victim had died.

'Okay, um wow I'm so sorry about that, um, that was not my intention,' Stevens cold-heartedly tells them.

'I've been mentally going through a lot,' she bleats. 'I have bipolar depression and I'm just going through a lot right now.'

When officers returned to the home for a second time, Stevens and Janine faced more questions 

The pair were delivered the news Bocanegra had passed away when Stevens was heard telling police 'I'm not that person' 

Janine too was hauled down to the precinct where she repeatedly laughs as she recounts what took place seemingly unaware that her freedom is hanging by a thread.

'So she's coming and we go and she comes to the house you know its a big fight, a big fight. 

'So um after the fight we took her phone we were going to her husband to let him know.

'You know, just stir some,' she giggled.

'She starts banging on the door like crazy cos, you know, we got her phone. 

'She gets her phone back yeah so, I don't know how she left like I wasn't watching after that cuz my brother was mad as hell and you know he don't want me in the business.

'I was already in it too much, so he's like on my a** so I'm just like 'okay'.'

Daniel Gonzalez was seen on bodycam discussing the incident with police. Officers later told him that his co-worker with whom he was having a relationship with on the side had not made it 

Stevens' accomplice Janine Gonzalez, 17, filmed the attack on her phone and laughed and giggled through a police interview after learning of Bocanegra's death

But her face turned to horror when her interviewer informed her that she too was being charged with murder

In the other interview room Stevens' head falls to the table as she is left alone momentarily with a homicide charge now hanging over her.

'I don't go out looking to harm anybody,' she tells detectives.

'It wasn't my intention to even get into an altercation with her today.'

Janine's grin freezes on her face and changes to a look of horror as her interviewer calmly informs her that she too is being charged with murder.

'Me!' she gasps.

'Whoa, that's, that's, that's too bad.

'No, no, no, no, what? Murder? I barely laid hands on her.

'All I did was pull her hair.'

Bocanegra's sister Jessica Rochce said the injuries inflicted were so severe 'she couldn't breathe out of her mouth' and doctors needed to 'put a tube in'. Bocanegra's son was seven years old when his mother passed away
