Cause of fire that killed animals at wildlife park unknown

The state fire marshal's office says it can't say what caused a barn fire that killed 10 animals at an Ohio wildlife park

The Nov. 28 blaze broke out in the southwest corner of a barn at the African Safari Wildlife Park in Port Clinton, killing three bongos, three giraffes, three red river hogs and a springbok.

Springboks and bongos are types of antelope. Officials captured a loose zebra and a giraffe that escaped.

The cause is undetermined given extensive damage to the building, state fire officials said. It's also unknown whether a power outage the day before was connected to the fire.

Port Clinton is on Lake Erie in northern Ohio, between Toledo and Cleveland.
