EMMAUS, Pa. -

A 31-year-old Emmaus man who threatened to kill his live-in girlfirend and her family --  while engaged in "yelling, fighting and tumultous behavior" --was arrested by borough police Tuesday.

After threatening his girlfriend, Kenneth Edwin Moser III attacked his own mother.

Now he is in Lehigh County Prison, with his bail set at $25,000.

At 702 p.m. Tuesday, an Emmaus police officer responding to a report of an assault found the female victim in a 2007 Honda Pilot, which was parked in the lot of the district court office at 106 Main St. in the borough.

The victim was upset and shaking.

She told the police officer that Moser, her live-in boyfriend, was acting very strange and arguing with her when she picked him up from work.

Without warning, he grabbed the steering wheel of the Honda and swerved the SUV into oncoming traffic in the 100 block of Main Street.

The terrified victim pulled into the district court parking lot.

She told police Moser was screaming at her and flipping out.

He began punching the SUV's dashboard, then the windshield, smashing it from the inside.

He threatened to kill her and her whole family if she called the police.

The victim fled from the vehicle and ran east on Main Street, while calling 9-1-1.

Other Emmaus police officers were dispatched to the home of Moser's mother in the 100 block of W. Berger Street in the borough.

At that address, they were directed to the rear of the property by a neighbor who was yelling "out back, out back!"

In the backyard, they found the defendant being detained by another neighbor.

Police secured Moser, whom they described as irate, violent and obviously intoxicated.

They learned from Moser's mother that he was "out of control" when he arrived home and demanded that she take him some where.

When she refused, he grabbed her by the neck and pushed her to the ground on her hands and knees, threatening to kill her if she didn't do what he was telling her.

At that point, the neighbor heard yelling and intervened, holding onto Moser in the backyard until police arrived at the home. Moser tried to atack that man, including by biting him.

The defendant's mother received minor injuries to her arms and neck and her shirt was torn in the attack.

The neighbor who subdued Moser received minor injuries to his neck, face and back, including a bite from the defendant.

Moser admitted to police that he had consumed several beers after work, before being picked up by his girlfriend.

Moser was charged with recklessly endangering another person, terroristic threats, simple assault, public drunkenness, harassment, disorderly conduct and criminal mischief.

Police estimated the cost to replace the windshield on the Pilot at $700. The SUV is owned by the mother of the girlfriend.
