A Coral Springs man is accused of choking his ex-girlfriend, then soaking her in a foul mix of human waste and condiments that he allegedly packed into her backpack as “payback,” according to police and court records.

Daniel Edward Niemiec, 20, is facing multiple domestic-violence charges tied to two separate incidents that investigators say started in early June and flared up again late last week. Court documents describe both the nonconsensual choking and the soiled-backpack incident as part of an alleged pattern of escalating abuse.

What police say happened

According to an arrest report, the first incident unfolded on June 2 during a sexual encounter, when the victim told officers she asked Niemiec to stop and he responded by slapping her. Detectives say a relative later emailed a tip that prompted a deeper investigation into the relationship, and that a follow-up argument on Tuesday “escalated” into strangulation, leaving the woman gasping for air before he let go, as reported by Local 10.

How the backpack came into play

After the confrontation, the woman left to stay with a friend. She told police that when she returned the next day to pick up her belongings, Niemiec met her outside holding her backpack, then dumped its contents all over her.

Court records reviewed by the Miami Herald state that Niemiec had filled the bag with feces, urine, ketchup, hot sauce and other unidentified fluids, which made “deliberate contact” with the victim when he emptied it.

Charges, bond and court limits

Authorities arrested Niemiec and charged him with one count of domestic battery by strangulation and two counts of domestic battery, according to a probable-cause affidavit reported by the Tampa Free Press. Jail records show he posted $4,000 bond.

As a condition of release, court records state that Niemiec is subject to a mandatory no-contact order involving the victim and must wear an electronic GPS monitor while the case moves forward.

What the suspect told investigators

During questioning, Niemiec allegedly admitted slapping the victim and told officers he had been “testing something new,” according to investigators. He also allegedly said that he sometimes “cannot control” his anger.

As for the backpack, Niemiec told detectives he had defecated and urinated in it as “payback” because he believed his ex had cheated on him, the arrest report obtained by Local 10 says.

How Florida treats strangulation cases

Under Florida law, domestic battery by strangulation is prosecuted as a felony. The statute defines battery by strangulation as knowingly impeding another person’s breathing or blood circulation and classifies domestic strangulation separately when the alleged victim is a family or dating partner.

As outlined by the Florida Senate, domestic battery by strangulation is a third-degree felony that can carry up to five years in prison, along with fines, under state sentencing guidelines.

Victim response and local help

The victim declined medical treatment but “was physically shaking” while speaking with officers, according to court records reviewed by the Miami Herald.
