Evidence: destroyed.

"An early morning house fire in San Jose has been linked to a mass shooting at the VTA rail yard Wednesday. The San Jose Fire Department received a call at 6:36 a.m. for a structure fire on the 1100 block of Angmar Court, a quiet, dead-end residential street near the East Capitol Expressway exit from Highway 101. The fire was knocked down about an hour later.

"Fire damage to home on Angmar Ct described as heavy," the department said in a statement. "The structure is currently uninhabitable." San Jose Mayor Sam Liccardo confirmed that the home is linked to the shooter.

Reporters from multiple local news stations posted images showing San Jose police officers blocking off Angmar Court and checking with people coming in or out of the street. NBC Bay Area reported no one was found inside the home and a large amount of ammunition was discovered. A bomb squad is also at the home. The FBI is investigating both the VTA shooting and the house fire."
