Rochester, NY (WKBW) - The two firefighters shot and injured in the Webster Christmas Eve Ambush have been released from the hospital.

Joseph Hofstetter and Theodore Scardino were released from Strong Memorial Hospital around Noon on Saturday.

Two other volunteer firefighters, Michael Chiapperini and Thomas Kaczowka, were killed in the attack.

In the days since the ambush, a new online White House petition has reached its goal. The petition urges the Obama administration to award Chiapperini and Kaczowka Medals of Freedom.

As of Saturday night, more than 26,500 signatures have been collected for consideration by the White House.

That's more than 1,500 signatures than was needed.

Webster police says William Spengler set fire to his house and car to lure firefighters into a deadly trap.

When first responders arrived, Spengler hid and shot the firefighters.

The fire spread to multiple nearby houses, leaving a total of nine homes destroyed or uninhabitable.

Police say a suicide note left by Spengler, in which he said "I still have to see how much of the neighborhood I can burn down and do what I like doing best: killing people."

Authorities believe another body found in Spengler's home was his older sister.
