MADERA COUNTY, Calif. (KFSN) -- The Madera County Sheriff's Office is investigating a shooting involving a Fresno County sheriff's deputy that left one person dead. It happened around 4 a.m. Thursday north of Millerton Lake. The deputy-involved shooting turned into a SWAT standoff after the suspects ran to a house.Fresno County Sheriff Margaret Mims said members of the HEAT team were conducting surveillance of a stolen truck and followed the vehicle from the Fresno area to the area near Road 216 and Road 210. Investigators say the two suspects -- a man and woman -- jumped out of the truck and ran to a home that they were familiar with. "The suspects realized that they were being followed. They parked and ran from the location here in Madera County," said Mims.Mims said law enforcement surrounded the house and established communication with a male resident, who was not the suspect, for about an hour. A while later, deputies saw the resident in the window with a rifle. The man became hostile and pointed the rifle at law enforcement, and a Fresno County deputy fired two shots at the man and killed him, authorities said.Mims said the female suspect, who was inside the stolen truck, was taken into custody. The other suspect, who was the driver of the truck, is outstanding.
