Last week, The BoomBox reported that 23-year-old aspiring rapper Tony Trapz, born Anthony Spencer, was murdered at a recording studio in Toronto. Police are still searching for his killer one week after his death. However, a woman caught on video at the scene of the crime may give authorities some much needed information about the tragic incident.

The Toronto Star reports that Det. Sgt. Gary Giroux has released video -- seen here -- and audio recordings of a "mystery woman" who was at the scene of the rapper's shooting death. Police are searching for the woman in hopes that she can give more information in the case. Since Jan. 21, witnesses who dropped Spencer off at the hospital have not been cooperative with details.

In the surveillance video, the unidentified woman, who gave a name of "Ashley" to a cab company, is seen walking into the studio where Spencer was located at 12:42AM. Hours later, she calls a cab company, identifies herself and a gunshot can be heard in the background. She is seen leaving with two men wearing hooded sweatshirts at 4:32AM.

According to Giroux, the woman wanted in connection to the murder is "either with [the two suspects] or against them," and the evidence against her leaves the option of contacting police or facing prosecution.
