Would-be assassin's gun purchased by suspect's dad, bomb-making materials reportedly found in home

The firearm used by Thomas Matthew Crooks in the attempt on former President Trump's life was legally purchased by the suspect's father, Fox News has confirmed. 

Authorities have recovered the weapon and the family is cooperating with law enforcement, according to sources familiar. 

One source said family had access to several guns and authorities are investigating whether the suspect himself had access to other weapons as well. 

Law enforcement officials told the Associated Press bomb-making materials were found inside Crooks' car and in his home.
