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.
A judge on Monday ordered that Mista be held without bond. City Prosecutor Jim Melle called Mista a flight risk, saying he has used relatives to evade authorities in the past and he is not a U.S. citizen. A message seeking comment was left with his attorney.
Killed in the shooting were 26-year-old Elmore police Officer José “Andy” Chávez, 28-year-old bartender Ramiro Sánchez, and a 25-year-old customer, Daniel Ramírez. A fourth man shot at the bar, 25-year-old Ramiro Arreola, was taken a hospital with injuries believed to be non-life-threatening.
``A little scuffle broke out, he felt he needed to pull a gun out,'' Arreola told The (Fremont) News-Messenger. ``Just started shooting everybody, innocent bystanders.''
Manuel Chávez, the slain officer's uncle, said the shooting occurred after a man approached Chávez's wife and began arguing her with, then punching her in the face.
``My nephews jumped on this guy,'' Manuel Chávez told the Sandusky Register.
The man then left the bar and came back in a side door and began shooting, Manuel Chávez said.
Wiersma said Sunday that the shooter had been in the bar for some time and may have gotten into a fight with another patron ``when things went horribly wrong.''
Andy Chávez had been at a birthday party for his daughter on Saturday night when Ramírez suggested they go out to celebrate the officer's birthday, which had been earlier in the week, Manuel Chávez said.
The officer and his wife had two young children. He had been with the Elmore Police Department for more than two years and was an ``exemplary'' officer, Sgt. Jeffrey Harrison said in a statement.
