UPDATE | Arrest made in Ohio bar shooting that killed 3

FREMONT, Ohio (AP) — An off-duty police officer celebrating his birthday and two other men were shot and killed at a northern Ohio nightclub over the weekend after an argument erupted when the shooter punched the officer's wife, relatives said.

Police arrested 33-year-old Igmidio Mista of Fremont on this morning and charged him with opening fire inside the Last Call Bar early Sunday.

A warrant issued just hours before the arrest charged Mista with three counts of murder. It wasn't immediately clear who his lawyer was.

Officers found Mista at a home in Fremont, police said. He came to the door after a relative had met the officers, and he was taken into custody without incident, police Chief Tim Wiersma said.

Killed in the shooting were 26-year-old Elmore police Officer Jose Andy Chavez, 28-year-old bartender Ramiro Sanchez, and a 25-year-old customer, Daniel Ramirez. A fourth man shot at the bar, 25-year-old Ramiro Arreola, was taken a hospital with injuries believed to be non-life-threatening.

The shooting occurred after a man approached Chavez's wife and began arguing her with, then punching her in the face, said Manuel Chavez, the officer's uncle.

"My nephews jumped on this guy," Manuel Chavez told the Sandusky Register.

The man then left the bar and came back in a side door and began shooting, Manuel Chavez said.
