There they found the deceased family of four who had all been killed in an apparent murder-suicide. 

All four had suffered gunshot wounds and investigators have subsequently revealed that Huber was the main suspect. 

Police believe that Huber killed her husband, Adam, 50, and her two sons, Adam Jnr., 17, and Michael, 16, on or before March 4. 

Joan Huber was originally from Coolcuslaugh, Co Kerry. She moved to the United States around 30 years ago and several family members still reside in Killarney. 

Her late father, John Kelly, was a local historian and was once the president of East Kerry GAA club.

It has been a particularly traumatic time for pupils at Damonte High School in Nevada, where Adam Jnr. and Michael went to school. 

Five students at the school have been killed in just over a month, with two teenagers dying from a suspected drug overdose and one taking their own life. 

The tragic shooting of the two Huber boys brings that tally to five. 

The school was staffed with additional counselors and therapy dogs on Thursday to help students deal with the latest tragedy, according to local news agency Kolo8. 

Police say that they are still establishing a motive for the murder-suicide and say that the investigation remains ongoing.
