Nov. 9 (Bloomberg) -- Tatsuya Ichihashi, the only suspect in the Lindsay Ann Hawker murder investigation, may have been working on construction sites in Osaka until Oct. 11, the Yomiuri newspaper reported.

A person thought to be Ichihashi was living in a dormitory for 13 months in Ibaraki, northern Osaka, the newspaper said, citing unidentified investigators and the construction company that reportedly paid for the accommodation. Fingerprints found in the dormitory matched Ichihashi’s, the report said.

The man under investigation was recruited by the company in September 2008 in Osaka’s Nishinari area, and saved more than 1 million yen ($11,000) in wages, the report said. The money may have been used to pay for plastic surgery in Nagoya, central Japan, the Yomiuri said.

Nishinari is a district where shelters and soup kitchens serve hundreds of day laborers and homeless people. Ichihashi, 30, has been on the run since March 2007, when police found the body of Hawker, a 22-year-old British woman, buried in sand in a bathtub in his apartment in Ichikawa, east of Tokyo.
