As a new year begins, Toronto police are asking the public not to forget about a number of still unsolved crimes from 2011.

While officers were successful in cracking several cold cases this past year, including two this month alone, a number of high-profile crimes from the past 12 months are still without resolution.

That's unless tips come in from the public that allow officers to crack the cases before they become cold.

"There is always a family, there are always loved ones of the victim and it is important to find out who is responsible, so we can provide closure for them," Const. Tony Vella told CP24.com during a year-end interview. "It is very difficultly having a loved one victimized, not to mention not even knowing who is responsible."

Toronto Police Services has a cold case squad and as a result, no file is ever entirely closed, but as the days turn into months it becomes increasingly hard to solve crimes, Vella said.

That's why police are urging the public to keep recent unsolved crimes near the top of their minds in 2012, should something or someone jog their memory.

"We have to continue (investigating) until we find out who is responsible," said Vella. "It could be 30 or 40 years from now. We won't stop."

The following is a list of some of the top unsolved crimes from 2011:

Explosives found in Etobicoke party store

In October, the Amazing Party and Costume store, near Kipling Avenue and the Gardiner Expressway, was forced to close its doors after seven packages of explosives were found inside. The devices were destroyed by a police bomb squad, but could have caused bodily harm or even death if they had went off in the store, officers said at the time. The intermittent closures of the store during its busiest sales period translated into a loss of $500,000 for owner Shawn Hamilton.

Update: A reward of $10,000 posted by Hamilton has not yet provided any leads that would justify charges. The store, meanwhile, is upgrading its cameras and security system and is planning to hold a formal reopening in the new year to help keep the case in the limelight.

Bloodshed at community barbecue

Jermaine Smith, 28, was fatally shot while attending a back-to-school barbecue near Dundas Street and Scarlett Road on August 28. The shooting occurred within steps of a playground filled with children and just metres from the barbecue, attended by 150 people, Det. Sgt. Wayne Banks said at the time. Smith had a two-month-old son and was not believed to be involved in any gang activity.

Update: The case is still unsolved according to Const. Tony Vella and police have not released a description of the suspect, other than to say they are looking for a black male. In September, Smith's family released a statement in which they claimed Smith "died a hero", shielding children from a hail of gun fire.
