Police have arrested a woman wanted for questioning in connection to Calgary's first homicide of 2010.

Natalie Renee Louise Vinje was found in downtown Calgary on Tuesday evening.

The 23-year-old is being interviewed by detectives with the Homicide Unit.

On January 19th, the body of Serafino Virgilio was found in an SUV in the 200 block of Falshire Way N.E.

Investigators believe the 57-year-old was killed two days earlier in his home before his body was hidden inside the Denali.

Police were looking for the man's roommate and Vinjie for questioning.

Investigators are still asking for help finding Pablo Rodrigo Russell. He is described as Hispanic, 180 cm (5'11") tall, and 80 kg (176 lbs). The 33-year-old also goes by the name Paul. He has a noticeable scar on his nose and a tattoo of a dragon on his upper back.

Police say they had Russell in custody for questioning shortly after the homicide but he would not cooperate and they had to release him.

Anyone with information about the homicide, or knows where Russell is, can call the Homicide Unit's tip line at 403-206-8877.
