2 charged with first-degree murder in 2012 homicide

Two people face first-degree murder charges in connection with a killing that saw a body left on an Etobicoke lawn last year, while police say four additional people face charges stemming from the investigation.

Edwin Villan, 33, was found dead on the morning of Sept. 16, 2012. Toronto police said he had been shot in the head.

Months later, police revealed that Villan's killer had driven away in a Nissan Pathfinder that belonged to the victim, which had distinctive wheels, rims and tires.

Two days after Villan was killed, police responded to an arson call and found the vehicle ablaze.

When police revealed the details about the Pathfinder in March, investigators were hoping to hear from witnesses who saw the vehicle driving around the area of Pearson International Airport after Villan was killed.

On Thursday, police issued a news release saying that six people had been charged in connection with the investigation into Villan's death:

- Michael Seecharran, 22, of Toronto, faces a charge of first-degree murder, as well as charges of conspiracy to traffic cocaine and possession of cocaine for the purposes of trafficking.

- Karla Garcia-Woltke, 41, also of Toronto, faces charges of first-degree murder and conspiracy to traffic cocaine.

- Patraj Seecharran, 42, of Toronto, faces a charge of being an accessory to murder after the fact.

- Claudia Garcia-Woltke, 36, of Maple, Ont., faces a charge of attempting to obstruct justice.

- Lazaro Carias-Caseros, 31, of Toronto, and Jenny Sorto Garcia, 18, of Toronto, each face a single count of conspiracy to traffic cocaine.

Police said that all six suspects were due to appear in court on Thursday.
