The mother of three of the children who were inside the home when Shannon Gooden opened fire and killed three Burnsville first responders says she was subpoenaed and testified in front of a federal grand jury.
An investigation is underway to determine whether the gunman who shot and killed three Burnsville first responders obtained one of his weapons through a straw purchase.
The owner of a Burnsville gun shop said Tuesday that a firearm connected to the deaths of two police officers and a paramedic last week has been traced to his store, and appears to have been obtained by a straw buyer.
