More than 18 months after she reported his death, a 52-year-old Vancouver woman has been charged with the murder of William Canning.

Nirmala Arjun was taken into custody Thursday morning and has now been charged with second-degree murder in the death of her 65-year-old acquaintance.

Const. Lindsey Houghton told ctvbc.ca that Arjun called police to report Canning's death in an apartment in the 2100-block of Cassiar Street on January 29, 2009.

She was taken into police custody for questioning at the time, but released later the same day.

"Homicide investigations are typically very complex and can take a long time, but now we've made an arrest, and we're very happy about that," Houghton said.

He added that police are not releasing the manner in which Canning was killed.

Arjun is scheduled to appear in Vancouver provincial court on Friday.
