'Enraged titan' Adam Montgomery is heard in a jailhouse call saying FBI agents searching for his daughter's body were 'wasting their time' as jury deliberates whether he killed tragic Harmony, 5, by punching her in the head then hid the body

The father accused of killing his his own daughter by repeatedly punching her in the face and then hiding her body has said that the FBI agents looking for her are 'wasting their time'.

Adam Montgomery, 34, is on trial for allegedly murdering his five-year-old daughter Harmony, who was blind in one eye, in 2019 after getting angry with the little girl when she had a bathroom accident in the car.

Her body has never been found. 

On Monday The New Hampshire court where the trial is happening, heard an audio of a prison phone call from 2022 where Montgomery tells a friend: 'They had the FBI and everyone there digging up the river, dude. They wasted their time.

'Like, way to just waste taxpayers' money, I guess.'

The prison conversation was heard just as the court wrapped up the ongoing case's proceedings for the day on Wednesday. The jury is now out to deliberate on if he is guilty of the murder.

Authorities have been working tirelessly to try to find Harmony's body, who was last seen alive in 2019.

The Sun reported on Montgomery's prison phone call where he said police are 'wasting their time' looking for the body.

A public record request by WMUR TV revealed that the prosecutors at the court last year accused Montgomery of spending three months moving Harmony's body around in an effort to keep her hidden from the police.

According to the report, in earlier hearings, prosecutors have alleged that the evil accused child-killer moved the body from container to container and place to place as her body decayed.

The locations included the trunk of a friend’s car, a cooler in the hallway of his mother-in-law’s apartment building, the ceiling vent of a homeless shelter and an apartment freezer.

Montgomery's estranged wife Kayla, step-mother to Harmony said that at one point the body was kept in a tote bag from a hospital maternity ward according to the same report.

Kayla, who is reported to have been there at the time of the murder, said she placed the tote bag in between her own young children in a stroller and brought it to her husband’s workplace.

Investigators allege that Montgomery finally disposed of the body in early March 2020 with a rented moving truck.

His defense attorneys have attempted to place the blame on his estranged wife, Kayla Montgomery, Harmony's step-mother, who was allegedly with him at the time.

However, Montgomery is reported to have previously said 'I 'f***** up, I f***** up, I f***** up' and not WE f***** up.

Prosecutor Ben Agati labelled Montgomery as an 'enraged titan' for his heinous crime.

He said: 'Adam Montgomery was no loving father. He was an enraged titan who had no business being around Harmony.

'On the day of Harmony's death, all he has is his car, his rage, his fists. After he learns Harmony, soiled herself in the car.

Montgomery is reported to have said: 'I think I really hurt her this time' after the fatal punch - and went on to say: 'I felt something'.

Defense attorney Caroline Smith, trying to mitigate the defendant's punishment, claimed he was influenced by Kayla.

Smith said: 'Adam did not kill his baby girl. He made horrible and criminal decisions after Harmony's death to keep his family together.'

'Adam did some very, very bad things, but he did not kill his daughter.'

Montgomery is facing charges of second-degree murder, second-degree assault, and witness tampering after pleading guilty to abuse of a corpse and not telling the truth in earlier stages of the ongoing trial.

Kayla is currently serving an 18-month sentence for perjury after employment records proved her alibi to be a lie. 

However, one testimony by the step-mother that is unfortunately thought to not be a lie is her account of what happened in the car on the dreadful day in 2019.

She said Montgomery 'kept punching her' on the way to Burger King, pausing at several stop lights to reach behind him and punch her in the head again.

'Adam kept saying, shut the f*** up, stop crying,' she said, adding that when she tried to stop him, he gave her an 'evil crazy eyes look' that scared her off.

'That was one of the first times I saw him look at me like that. But not the last,' she continued.

She said her two sons in the car with them, aged 11-months and 2-years-old at the time, had 'no idea' of the horror unfolding in the car next to them.

After allegedly delivering the fatal blow, Kayla said they got Burger King for themselves and her two young sons in the car, but not Harmony.

She claimed Adam had covered Harmony in a blanket, but was still making a 'moaning noise' before eventually falling silent.

The jury have been deliberating since Wednesday evening and are yet to reach a verdict.
