Toronto police have launched a new homicide cold-case website that allows users to access decades-old records.

The launch of the new website was announced by Toronto Police Chief Mark Saunders during a news conference Wednesday.

The website lets users search cases by year or by victim's name. Users can access information on cases dating back to 1959, including how to contact investigators with more information.

"We have taken the time to re-tool the web page to make it more interactive and informative," Saunders said Wednesday.

"We would encourage the public to go to the website and use social media to spread the word on the individual cases and people wanted for murder."

In the coming weeks, Toronto officers will be releasing short video clips on the website, hoping to spark the memories of those with more information on cold cases.

Appeals were released Wednesday on three Toronto cold cases, from 1987, 2003 and 2010.

The first video was an appeal for more information on Rosaleen Wallace, wanted on a Canada-wide warrant in connection with the death of a 5-year-old boy. The boy died on Feb. 17, 1987. 

Police also published a video about the murder of 32-year-old Cassandra Do, a transgender escort who was found dead on Aug. 25, 2003. Do had been strangled in the bathtub in her apartment, and it is believed that a client may have been responsible.

Officers are also looking for more information in the death of Nanthieashan Dharmaratnam, who was struck by a car on March 13, 2010. A Canada-wide warrant has been issued for the arrest of Seran Kasilingham in connection with the case.
