Dramatic footage of a fatal shooting of a man that stemmed from a heated argument with his father-and-son neighbors over where to dump a mattress has emerged.

A West Texas man was shot and killed on September 1 and a father and son have been arrested on murder charges over what a police chief calls a neighborhood dispute about trash.

Police responded to calls about shots fired around 10.15 a.m. and located the victim, 37-year-old Aaron Howard, who died at a hospital.

John Miller, 67, and 31-year-old Michael Miller were arrested on murder charges over the death of Howard.

Howard was shot dead as his brother and fiancee witnessed the horrific incident first-hand, according to the Star-Telegram.

Howard’s fiancee, Kara Box, filmed the argument which led to the shooting on her cell phone.

'I stepped in between Aaron and John (Miller), then my ears started ringing from the gunshots,' Box said.

'I just screamed and screamed.'

The argument took place in an alley behind Howard’s home on Don Juan Street in Abilene, which lies 150 miles west of Fort Worth.

Authorities said the confrontation had started days before and reached a boiling point on this particular Saturday.

Box and Howard had moved next door to the Millers in April. They had never encountered them face to face until September 1.

'We had thrown out a twin mattress in a dumpster in our alley a few days before the shooting,' Box said.

'You have to have the mattress in the dumpster or they will not haul it away.'

On the morning of September 1, Box and Howard noticed that the mattress was back on their property. So they tossed it back in the dumpster.

Box said that at this point John Miller came to the alley, took the mattress out of the dumpster, and tossed it back onto her and Howard's property.

Howard then told Miller to put the mattress back into the dumpster. Miller refused, then added some foul language.

'That’s when John (Miller) pulled a pistol out of his shorts,' she said.

Box said that Howard's nieces and nephews, who were in the backyard, were watching as this unfolded.

'Aaron goes into pappa bear mode,' Box said.

'A man has just pulled a gun on his wife, his brother, his nieces and nephews.'

Just before Howard is shot, Box tries to get between the three men. ‘You can see that I step between them and I said, “You’re not gonna shoot my husband”,’ she told KTXS-TV

Howard and Miller engage in a tense conversation, during which Miller's son, Michael arrives with a shotgun.

Howard, who is unarmed, receives a baseball bat from his brother, though he does not use it, according to Box.

Box then provided the footage to a local television station - KTXS-TV.

It shows both John and Michael Miller holding firearms.

The father has a pistol in his right hand while the son, standing just a few feet behind him, is gripping what appears to be a shotgun.

The two shirtless men are holding the weapons while engaged in a verbal confrontation with Howard.

Howard is heard in the video yelling at the Millers to put their guns down.

‘If you come closer to me, I’m gonna kill you,’ John Miller is heard telling Howard.

'If you come within 3 feet of me, I’m going to kill you,' Miller tells Howard.

‘Hey, did you hear him say he’s going to kill me?’ Howard says to Box as she’s filming.

‘People deserve to know what actually happened,’ Box says when asked why she decided to release the footage to a television news broadcast. ‘They deserve to know that John and Michael Miller are murderers’

‘Yes,’ Box replies.

‘I’m at the dumpster,’ Howard says before turning to the Millers. ‘Put the gun up and go inside!’

The argument becomes even more heated as both sides make threats against the other.

Just before Howard is shot, Box tries to get between the three men.

‘You can see that I step between them and I said, “You’re not gonna shoot my husband”,’ she told KTXS-TV.

Box has since moved from the home on Don Juan Street near where the shooting took place. She is seen with her late fiancee in the above file photo

Box said that John Miller ‘fired past my head.’

She then ran toward her husband amidst the chaos. In total, four shots were fired.

Finally, John Miller pulls the trigger on his pistol, though this is not captured by video.

Moments later, his son, Michael Miller, also shoots Howard. This is clearly evident in the footage.

Howard suffers gunshot wounds to his head and chest.

'No, no, Aaron!' Box screams as she runs toward her fiancee.

According to Box, John Miller walks up to her and puts his handgun against her head, ordering her to get down on the ground.

'I ran to Aaron and for a second I thought he was going to be OK, but he didn’t make it,' she said.

‘People deserve to know what actually happened,’ Box says when asked why she decided to release the footage to a television news broadcast.

‘They deserve to know that John and Michael Miller are murderers.’

Taylor County District Attorney James Hicks only learned of the existence of the video from KTXS-TV.

‘Video evidence like this is always graphic and very difficult to watch,’ he said in a statement.

‘But it is consistent with the charges.’

When asked what message she had for John and Michael Miller, Box said: ‘You deserve to spend your lives in prison.’

Box has since moved from the home on Don Juan Street near where the shooting took place.

John and Michael Miller have been freed on $25,000 bond.
