The man who drowned Sunday afternoon in the Columbia River has been identified as Battle Ground police Officer Michael M. Molzahn, 41, of Battle Ground.“He was really liked in the community. A terrific motor officer,” Chief Robert Richardson said this afternoon. “Everybody in Battle Ground knew Mike.”Authorities said Molzahn jumped from a boat in the Columbia River off Government Island and struggled against the current and the cold. Those in the boat could not reach him, a person on a personal watercraft reached him later and took him to the island. A Portland fireboat then took Molzahn to Vancouver’s Steamboat Landing, where efforts to revive him were unsuccessful. The accident happened about 5:30 p.m.He was hired by the Battle Ground Police Department in March 2000 after serving for at least two years as a reserve office, said Lt.
