An autopsy is now complete on a 29-year-old Ottawa man found dead in a Denver hotel room on Monday.

Although Denver police haven't yet said how Saleman Abdirahman Dirie died, authorities told reporters they found one pound of sodium cyanide near his body.

Police say it appears Dirie was dead for several days before his body was found in room 408 of the Burnsley Hotel in downtown Denver, located about four blocks from the State Capitol.

The FBI and the U.S. government's anti-terrorism agency are assisting in the investigation.

"Our joint services task force is involved in this simply because the victim here is from another country and it just kind of makes sense that our terrorism guys take a look at this," FBI special agent James Davis told the local CBS News television station in Denver.

Ottawa's Somali community in shock

Meanwhile, members of Ottawa's Somali community, which Dirie belonged to, are in shock after learning of his death.

"I don't know what happened. The community don't know what happened but I think the community do care. One of their members who travelled to Denver lost his life there," Abdirizak Karod told CTV Ottawa on Wednesday, adding that Dirie's family left for Denver immediately after learning of his death.

Police are now waiting on toxicology results to determine how Dirie died and whether cyanide played a role in his death.
