UPDATE: Porter Ranch Man Gets 7 Years in Shooting Death of Friend

A Porter Ranch businessman was sentenced today to seven years in prison  for the alcohol-fueled shooting death of a childhood friend who worked as an NBCUniversal executive.

was also ordered to pay $3.7 million in restitution to the victim's family.

The defendant pleaded guilty in September to involuntary manslaughter in the shooting of 32-year-old , who was gunned down in Armstrong's garage.

Attorneys said both men had been drinking.

"Guns and alcohol never mix," said Judge Beverly Reid O'Connell, adding that her sentence was partially based on the fact that the defendant showed no remorse before today's two-hour hearing.

Armstrong sat hunched over, revealing no emotion, as Kaplon family members and friends angrily and often tearfully excoriated the defendant and his wife.

"You should have killed yourself. Not a second goes by that I don't wish you were dead," widow Kristi Kaplon told the defendant.

She asked O'Connell to "punish this devil and send him to the harshest prison."

The men's wives were once best friends, defense attorney James Blatt said, and the husbands had known each other since the fifth grade. They attended Chatsworth High Schol together.

Kaplon had gone to Armstrong's home in the gated Sorrento neighborhood in Porter Ranch the night of March 18 to get a free haircut from the defendant in order to save a few bucks, the victim's family said.

A drunken Armstrong approached Kaplon with an AR-15, a "fearsome" civilian version of the M16 rifle, placing the muzzle against the accountant's chest, Deputy District Attorney Jeffrey Stodel said.

Armstrong "was trying to be a tough guy," making "a sad attempt to be funny," when he pointed the loaded weapon at Kaplon and twice pulled the trigger, Stodel told the court.

After the shooting, "one of the first things he did was lie and lie and lie" to police in order to "protect himself" and "lessen the impact of what he'd done," the prosecutor said.

But Blatt said afterward that the rifle went off when the two men accidentally bumped into each other.

In a brief, halting apology, Armstrong told the court that he loved the victim and never intended to harm his friend.

"Not a day goes by when I don't wish it was me and not him," he said.

After the judge pronounced sentence, Armstrong was immediately handcuffed and taken into custody as his relatives shouted, "We love you, Dave."

Armstrong was initially charged with murder, which could have brought a sentence of 25 years to life in prison.

The Kaplons had a toddler daughter at the time of the shooting, and the victim's wife was pregnant with twins.

"No one will ever know what happened that night in the garage but Dave and Brian," the widow said.
