Fremont, Ohio:
Police say a gunman opened fire inside a northern Ohio nightclub, killing an off-duty police officer and two other men and wounding a fourth.
Authorities say the shooting happened early Sunday at the Last Call Bar in Fremont. No arrest has been made, and detectives are working to identify the gunman.
Fremont police Chief Tim Wiersma says the shooter had been in the bar for some time and may have fought with another patron "when things went horribly wrong".
He identified the dead as 26-year-old Elmore police Officer Jose Andy Chavez, 28-year-old bartender Ramiro Sanchez and 25-year-old customer Daniel Ramirez.
A fourth man, 25-year-old Ramiro Arreola was taken to a Toledo hospital in critical condition.
Fremont is about 56 kilometres southeast of Toledo.
