Ontario Provincial Police officers on Friday resumed their search of Col. Russell Williams's home in Ottawa.

Police first executed the search warrant on Williams' home in the Westboro neighbourhood, west of Ottawa's downtown core, early Thursday afternoon.

The former commander of CFB Trenton is charged with murdering Jessica Lloyd and Marie-France Comeau, and sexually assaulting two other women.

The OPP said they have been receiving calls from other police forces in communities across the country where Williams lived about possibly looking into past cold cases.

However, the OPP said its main focus is on the current deaths and sexual assault cases.

"It's not going to be done in the short-time, it's going to be a very long process," said OPP spokesperson Sgt. Kristine Rae.

"As we get our details more analyzed, more looked at, then we'll start the other comparisons to see if there's anything we can help with other services or even in our own jurisdictions," she said.

CBC News learned this week that Williams led investigators to the body of Lloyd.

Sources told CBC that Williams provided a full statement to police, who are now looking at other unsolved cases based on that statement, including breaking and entering.

While police searched Williams' home, hundreds of Lloyd's friends and family members gathered at a Belleville, Ont., funeral home Friday for visitation. Lloyd's funeral is scheduled for Saturday.

Separately, it appears that Williams will not be entitled to money or legal support from the military. A Department of National Defence spokesperson told CBC that members of the Canadian Forces are not normally entitled to a government-paid lawyer for legal matters that fall outside the scope of their duty or employment.

DND also confirmed that Williams will continue to be paid, pending the outcome of any possible trial.

In keeping with Canadian law, a member of the military is presumed innocent until proven guilty at trial. However if that member of the Canadian Forces is convicted, he or she must reimburse pay received since the date of the arrest.
