Ontario Provincial Police have arrested a second person in connection with a homicide in Perth, Ont. on April 12, as two suspects charged with murder remain at large.

Police responded to Last Duel Park where 34-year-old Christo Allision Richards of Ottawa was found with life-threatening injuries. He later died in hospital.

As part of the investigation, OPP officers with assistance from the RCMP executed a search warrant at a rural property in Terrace, B.C. where two firearms were seized.

Police announced Wednesday that Lyna Du, 32, of Ottawa, was arrested and charged with accessory after the fact to murder.

OPP arrested a 46-year-old man from Perth on charges of conspiracy to commit murder as part of the investigation in May.

Two men charged with second-degree murder remain at large. Police believe Joseph Madore, 34, of Ottawa may be camping in a rural area of British Columbia.

The whereabouts of Brayton Kennedy, 28, of Ottawa are unknown, OPP say. Police said last month that Kennedy may still be in the Ottawa area or travelling with Madore.

Anyone who sees the suspects is being asked not to approach them and to contact police.

A homicide investigation continues. Police say anyone with information is asked to contact the Lanark County OPP.
