Walter Kostrzewski, 42, of 7 Revere Road, Darien, was charged with first-degree reckless endangerment, second-degree threatening, third-degree assault, interfering with an emergency call and second-degree harassment following an incident at his home on Thursday, April 22.

Police said officers responded to a 911 call at the home at 2:30 p.m. According to the report, Kostrzewski reportedly argued with the complainant, his wife, on Thursday morning, police said. Following the argument, the complainant took a shower in the master bedroom at 11 a.m., and claims Kostrzewski pulled open the shower curtain and pointed a pellet pistol at her head, police said. The complainant yelled for Kostrzewski to leave, and he exited, according to police.

Police said a few minutes later, Kostrzewski returned, pulled open the shower curtain again, and held the pellet gun within inches of the complainant's head. The complainant told police she heard a click, but there were no projectiles fired, according to police. The complainant told police that her husband said, "Next time it's going to be real," police said. She yelled for him to leave the bathroom again, and he did, according to the police report.

When the complainant finished her shower, she was uncertain where the gun was and called a family member to ask whether she should alert the police, according to Darien Police Capt. Fred Komm. Komm said Kostrzewski overheard the phone call and picked up on another extension, at which point the complainant hung up the phone.

The complainant then walked toward the front door with her car keys and purse to exit the house, at which point, Kostrzewski threw a telephone handset at her, striking her in the back, police said.

She tried to call 911 on her house phone, but police said Kostrzewski disconnected the phone line.

The complainant walked to her car, as Kostrzewski followed her out the door, according to police. She then left the premises, returning at 2:30 p.m., police said. In the few hours since the initial incident, she received approximately a dozen harassing phone calls and text message from her husband, according to the police report.

When she returned home, she found that her husband had left to go to his office in Milford, and she called 911 from her cell phone as she sat in the driveway, according to Komm. The police arrived at the home at 2:40 p.m.; upon searching the location they found the pellet gun in the drawer of a plastic chest in the laundry room, Komm said.

Officers called Kostrzewski at his office in Milford; shortly after they received a phone call from someone reporting to be Kostrzewski's attorney, indicating that Kostrzewski would not come into the police department that evening, police said.

Officers from the Darien Police department called the Milford Police Department to detain Kostrzewski until Darien officers could arrive. He was arrested, posted a $50,000 bond and appeared in Stamford Superior Court the following day, Friday, April 23.

He has not yet entered a plea, and is scheduled to appear in court again on Tuesday, May 18, according to the Stamford Superior Court Clerk.
