His family say he was last seen on Sunday when he left home – he had been expected later that day at a reception at his in-laws, but never showed up.
When he was reported missing by family and friends, police began searching for him - finding his body two days later in a small lake on the outskirts of the town.
His jacket was found hanging on a tree nearby.
A golden ring and his watch were also retrieved, said Misganu Wakgari, Nekemte’s head of security - adding that investigations were ongoing.
The groom was buried on Thursday, with many people on social media expressing sadness over the tragedy.
