Arson fire across the street, an angry man.

At 5:00am the neighborhood was awakened by two fire engines and four police cars (more came later). They remained there most of the day collecting evidence.
Someone poured an accelerant under the deck along the foundation. ON the deck directly above the fire was a LP BBQ grill and a spare full tank of LP.  The wheels on the BBQ grill were completely burned away... and the deck begin to burn. Other things stored under the deck were also burning, There were 3 mowers stored there with full gas tanks. The basement window broke from the heat. The metal siding was badly scorched.  In just a few more minutes it would have been too late.
.
. . While the family of 5 was sleeping, a neighbor noticed the flames and called the fire department...arrived in less than 2 minutes. Good thing because in 2 more minutes the LP tanks would have exploded, the baby sleeping on the other side of the wall would have certainly been instantly killed.
 
.. The reason the fire department got there so quickly is because a few minutes earlier they had been called to put out a pile of clothes and a bottle burning in a yard at a nearby house. When they got this call, they just drove around the block.
. . It seems that whoever set the fire caught his own clothes on fire and ran a short distance then peeled his clothes off and ran.
The Arsonist -
My neighbor across the street has a 19yr old family-friend renter. The renter has an ex-friend nobody likes. The next day the renter called that ex-friend, traced him to the hospital with burns.  The Police are on it.
