Vancouver police have released photos of two men who they believe may have information on a sudden death investigation. 

The police department says the two were seen alongside a 35-year-old man shortly before he was found dead inside his West End apartment on May 30. The cause of the man's death hasn't been confirmed, but police are investigating whether it was the result of a crime. 

鈥淲e believe these men may have important information about what happened, and we鈥檇 like to speak with them," Const. Tania Visintin said in a statement on Thursday (July 4). 

The men are believed to be aged 25 to 35 years old. At the time they were seen, one had a long brown and grey beard and was wearing a black hoodie, grey shorts and a grey baseball cap. The other man had a short goatee and was wearing a two-toned grey tank top with the number "86" on the front, as well as a light-coloured baseball cap. 

The deceased 35-year-old was discovered just after 11:30 a.m. on May 30, inside his apartment building near Davie and Bidwell streets. 

Anyone with information is asked to contact VPD.
