Waterloo Regional Police say they have arrested two men and two women involved in a break and enter at an apartment building on Lorne Avenue in Kitchener.

Detectives believe the incident and the apartment are linked to the weekend robbery and fatal shooting of Kitchener man Henry Jarsch, 31, outside a home in Wilmot Township.

Police say they believe Jarsch was one of a group of three men attempting to rob the house. 

The two other suspects in the robbery are Denis Gagnon and Scott White, both 37, of Kitchener. Police apprehended the two at a Kitchener residence, and they have now been jointly charged with robbery with a firearm. 

Police couldn't confirm whether the Lorne Avenue home was the same house where they encountered Gagnon and White. 

“The location is of interest to the homicide investigators who are currently investigating the first homicide of the year in Waterloo Region,” said police spokesman Olaf Heinzel.

The four arrested are Randy Matheson, 29, Jaclyn Miller, 35, Stephen Witter, 43 and Krista Freeman, 36.

Their charges include break and enter and obstructing justice.

Police continue to investigate the homicide. Crawford Lamka, 26, of Wilmot Township has been charged with second-degree murder and two counts of attempted murder. Claude Ouellette, a 52-year-old Kitchener man, was charged with being an accessory after the fact in relation to the homicide.
