(CBS) – Authorities issued a nationwide alert after a Crown Point man allegedly killed his 37-year-old ex-wife at a Schererville business before fleeing Saturday afternoon.

Alessandra De Moraes-Emiliano of Merrillville died from a gunshot wound at 2:25 p.m., the Lake County Ind. Coroner’s Office said. She was killed at the gift shop Edible Arrangements, which is located at 248 W. Lincoln Highway.

Saturday night, police were searching for Richard Kalecki Jr., 49, whom they identified as the victim’s ex-husband. They say surveillance video showed him committing the crime. He later fled in a red 2015 Toyota Corolla, with Ohio license plate FPN6779, police said.

“We have 25 detectives right now and a number of northwest Indiana police departments working this. We’re going to be working it through the night,” Robert Byrd, commander of the Northwest Indiana Major Crimes Task Force, told reporters at a Saturday evening news conference.

Kalecki had been scheduled to appear in court later this year on charges of sexual misconduct with a minor, police said.
