LEBANON, MO. (AP) -- Two more Springfield men have been charged in the weekend killings of three people in southwest Missouri.

The Laclede County Sheriff's Office said in a news release Monday that 18-year-old Steven Thomas Pyykola and 21-year-old Jacky Wong have been charged with three counts of first-degree murder in the deaths Saturday of 25-year-old Zachary Bryan Porter, of Elkland, 51-year-old Jeffery Smith, and his wife, 48-year-old Glenda Smith, of Laclede County.

They also face charges of armed criminal action and burglary.

Twenty-three-year-old Josh Reyes of Springfield was charged earlier with first-degree murder in Porter's death.

Jail officials didn't know if the men had lawyers.
