Dennis Riber had several hostile encounters with his ex-girlfriend after their relationship ended earlier this year, but the situation turned more violent Monday morning, according to police.
This time Riber showed up at her doorstep with a 20-gauge shotgun, a knife and 71 rounds of ammunition, Cheektowaga police said.
Police gave no clear reason for what set off Monday morning's three-hour hostage situation on Glenwood Court but said there has been continued fighting between Riber and his former girlfriend during the past several months.
Riber also had been drinking Monday and may have taken some pills as well, police said.
"Basically it's been a domestic situation that's been ongoing," Capt. Thomas E. Rowan said Monday night. "It's just a continuation of increasing domestic violence events over the past two to three weeks."
Riber of 23 Kingswood Drive, Cheektowaga, was charged with first-degree burglary, first-degree unlawful imprisonment, second-degree criminal possession of a weapon, first-degree criminal contempt and second-degree menacing, Rowan said.
Police had been called to the woman's apartment on Glenwood Court several times since February to defuse domestic violence situations between the two, Rowan said.
Police were called to the home last week, he added.
At about 7:30 a.m. Monday, police received a 911 call from the woman, who told them her ex-boyfriend was at her apartment armed with a shotgun.
Police Officers Frederick Roll Jr. and Timothy Szymanski arrived at the scene and were able to take the woman's 6-year-old son from the apartment.
Then Riber, who threatened to kill police officers if they did not leave the area, barricaded himself and his ex-girlfriend in the apartment by placing furniture against the doors.
Hostage negotiators and the Cheektowaga Police SWAT Team were brought in. Officer Thomas Krantz was able to talk Riber into leaving the apartment and surrendering at about 10:30 a.m., Rowan said.
The woman, who did not suffer any physical injury during Monday's incident, previously had filed for an order of protection against Riber, Rowan added.
She apparently broke off the relationship with Riber in February.
