31-year-old Igmidio Mista faces three counts of murder, as well as attempted murder, felonious assault, and possessing a firearm in a liquor permit premises. He pleaded not guilty to all six counts.
Mista is being held on a $5 million bond. Much of the evidence against him came from witness statements gathered by Fremont Police.
"Our detectives testified before the grand jury about the evidence they had collected," Fremont Police Chief Tim Wiersma said.

Police said Mista opened fire after a fight broke out at Fremont's Last Call Bar. 28-year-old Ramiro Sanchez, employed as the bouncer; 26-year-old Jose "Andy" Chavez, an off-duty Elmore Police Officer; and 25-year-old Daniel Ramirez, a patron of the bar were killed.
The bar is still closed, and the owner said it probably will be for weeks to come. The community continues to meet outside the bar, lighting candles and saying prayers.
Wiersma said the Fremont Police investigation is far from over. They're still trying to determine how Mista obtained a gun. Police say it couldn't have been in his possession legally, because he wasn't even in the country on a legal status.
"We have a lot of interviewing to do," Wiersma said. "Because we want to make sure everybody that was there has the chance to talk."
Mista is being held in the Sandusky County jail. His pretrial is set for April 21.
