Two young children were killed when an SUV drove through a Nevada home on Monday, according to police. Reno police are investigating what caused a 66-year-old man to crash into the South Reno home after he apparently failed to stop at an intersection. A mother, her 2-year-old son, 4-year-old daughter and teenage niece were in the house when the SUV rammed through it around noon (3 p.m. ET), killing the two youngest children, according to a statement from the Reno Police Department. The mother and teen were not injured, Reno Police Department spokesman Tim Broadway told NBC News.
