After several high profile shootings in Toronto this summer, police are appealing for information in a number of older investigations involving guns.

It's hoped that the appeals will lead to information that can bring a number of suspects wanted by police before the courts.

"We just need to find these people," says police constable Tony Vella.

The incidents that drew appeals from police on Wednesday range from November 2009 to May 2012 and the most serious is a murder.

Police are looking for information on the whereabouts of 23 year-old Robert Owen Cave, wanted for first degree murder in the shooting death of 24 year-old Kevin Phouthonesy on November 3rd 2009.

Vella had a message for the suspect who has been on the loose for almost 3 years.

"We are not stopping until we find you. It's only a matter of time."

Toronto police are also appealing for any information that might lead them to 24 year-old Adrian Pascal, a Toronto man wanted in connection with a serious shooting on Canlish Road near the end of 2011. On December 27th a man was shot and rushed to hospital with life-threatening injuries. Pascal is wanted for a number of alleged offences including attempted murder.

20 year-old Maurice Poku is wanted on a long list of firearms charges after an incident in December 2011 at 1771 Albion Road. A man and a woman were shot around 11:20 p.m on December 11th.

Police are also hoping for the public's help in finding 26 year-old Ibrahim Khiar of Toronto who is wanted on charges relating to the alleged sale of a firearm in August 2011.

The search is also on for 30 year-old Keri McKnight in connection with a discovery of a weapon and ammunition at a home on Goodwood Park Court in November 2011. McKnight is wanted for possession of a prohibited firearm with ammunition and careless storage of a firearm.

The most recent incident that drew an appeal from police came from this year. Police are trying to track down 23 year-old Abshir Olow of Toronto. He is wanted in connection with an incident on May 1st 2012 when a gun was discharged, but no one was hurt. The gun went off around 4 p.m. near Finch and Ardwick Blvd.
