Police investigating the murder of a 46-year-old Polish man found in Boston want to retrace his movements in the months before his death.
Marcin Stolarek's body was found in South Forty-Foot Drain on Chain Bridge Road on 12th January.
Lincolnshire Police have appealed for anyone who saw Marcin in the last four months to get in touch.
Adam Kaminski and Justyna Swiatek, both 26 of Union Court in Boston, have been charged with his murder.
Adam Maksajda, 33, of no fixed address, has been charged with perverting the course of justice.
All three appeared at Lincoln Crown Court on Monday and were remanded into custody, ahead of a provisional trial date in June.
