Boston police have determined that a body found floating near Rowes Wharf earlier this month was that of Eugene Losik, 25, a Lawrence man who went missing in the waterfront area in February.
But Losik's mother said there are still unanswered questions about the case.
"Of course, we have questions about what happened. We still don't know what happened. We don't know how he ended up in the water. It's devastating news for us and it doesn't answer anything. Actually, we have more questions now," said Zhanna Losik.
The body was found on Nov. 8. Losik went missing on Feb. 20.
Police said in a statement that the medical examiner had determined the body's identity and that cause and manner of death remained unknown.
Zhanna Losik said authorities had told the family that the identification had been made through DNA testing.
Eugene Losik, a graduate of the University of Massachusetts at Amherst who worked as an electrical engineer at Raytheon, was in Boston for a night of partying, staying with his girlfriend at the Marriott Long Wharf hotel.
Security cameras caught a picture of him leaving the waterside hotel alone just before 2:30 a.m., heading into the adjacent Christopher Columbus Park.
Rowes Wharf, where the body was found more than eight months later, is several hundred yards down the waterfront from the park.
