Bismarck police investigated three domestic assaults that lead to felony charges over the weekend.

Three men were arrested in the separate incidents. Another report remains under investigation, Lt. Randy Ziegler said.

n Joel Byzewski, 30, was charged with Class C felony terrorizing and Class B misdemeanor simple assault.

South Central District Judge Bruce Haskell set bond for Byzewski at $1,500 cash at the request of Burleigh County Assistant State's Attorney Justin Schwarz. Haskell ordered Byzewski to have no contact with the alleged victim.

Byzewski has been accused of assaulting and threatening a 23-year-old Bismarck woman who is pregnant with his child last week.

Ziegler said officers spoke to the woman, who they found hiding in a gas station bathroom in Bismarck while Byzewski was in the parking lot, around 4 a.m. Saturday.

The woman said Byzewski had been assaulting her for several days. She had bite marks on her back and her leg, bruises on her head and lip and a lump on her head.

Ziegler said a medical examination also revealed a subchorionic hematoma on the woman's uterus that possibly was caused by trauma.

The woman said Byzewski had been threatening to take her out by some tractors, rendering her unconscious, then leaving her to die under a tractor, Ziegler said. She said Byzewski did not want their baby, wanted her to have an abortion, and threatened to kill her and the child, Ziegler said.

The police report did not say how long the woman has been pregnant nor the condition of the baby.

n James Pennington, 51, was charged with Class Cfelony aggravated assault.

Haskell set bond for Pennington at $1,500 cash or surety and ordered him to have no contact with the woman.

Pennington is accused of covering his 51-year-old wife's mouth and nose during an argument early Tuesday morning, Ziegler said. He said Pennington's wife said the argument occurred after Pennington had been drinking all day. She said she fell out of a chair when he covered her mouth and nose, and he fell on her.

She went to a Bismarck hospital complaining of back pain from the incident.

Pennington told Haskell he has a medical condition that caused his behavior.

n Edward Smith, 43, was charged with Class Cfelony aggravated assault.

Haskell set bond for him at $5,000 cash. Smith said he is from Chicago and has been in Bismarck less than two weeks. He said he plans to demand a speedy trial. Haskell advised him to speak to an attorney.

Smith has been accused of trying to strangle his girlfriend while they stayed at a Bismarck hotel.

The woman, 34, said Smith was angry because she was planning to give her tax return to her sister, who has custody of the woman's child, Ziegler said.

She said Smith bit her leg and strangled her until she had trouble breathing.

n Police were called to southwest Bismarck at 11:56 p.m. Friday for a domestic dispute.

A 23-year-old Bismarck woman said she had been assaulted by her ex-boyfriend after he came to her home, Ziegler said.

He said the woman reported she and the 37-year-old Bismarck man argued through the screen door, then he opened the screen door and tried to strangle her.

The woman said she slapped him several times until he let her go, then she and a 28-year-old Bismarck woman, who also was at the home, pushed him out the door, Ziegler said.

He said the man was not located by police at the scene and has not been arrested.
