A Florida woman has been arrested after she allegedly wounded her ex-boyfriend and killed his new girlfriend during a custody exchange on Christmas day in a Walgreens parking lot, authorities said.

According to an arrest report obtained by the Alachua Chronicle, 38-year-old Amanda Marie Janzen led police on a 13-mile high-speed chase after the shooting incident in Gainesville before she was caught and taken into custody in Alachua.

Janzen and the male victim in the shooting have an 11-month-old child together, according to the arrest report.

After the baby was born, Janzen began to believe her boyfriend, who she had been with since September 2021, had been having an affair with the female victim for several years, and she called the female victim’s husband and told him about her suspicions, authorities said.

The baby’s father filed for custody of the baby weeks later, and on Dec. 20, a court ordered the two to share custody.

On Dec. 25, Janzen was to hand over the infant at a Walgreens in Gainesville.

Janzen drove to the drop-off location with the baby and her four other children. Along the way, she reportedly stopped and gave her oldest son her debit card, food stamp card and instructions on paying his cell phone bill, according to the arrest report. She then drove to the drugstore, arriving before the victims.

The victims arrived in the female victim’s car, with her driving and the baby’s father in the passenger seat, officials said.

Investigators were able to obtain security footage from Walgreens.

When the male victim exited his car, Janzen, with the gun behind her back, got out of hers, authorities said, and approached the driver’s side of the female victim’s car. According to police, she shot the woman three times, then circled around the vehicle and fired at the man three times, allegedly shouting, “You made this happen!”

Janzen then allegedly got back into her car and took off. A Gainesville Police officer who was nearby gave chase after hearing the gunshots and seeing a car flee the parking lot.

Other officers joined in the pursuit with speeds reportedly reaching around 100 miles per hour.
