Well, you certainly don’t see this everyday:

The June fire that destroyed the Spring home of Texas Supreme Court Justice David Medina was intentionally set, the Harris County Fire Marshal’s Office ruled Wednesday.
Investigators would not comment on a motive for the arson, which destroyed a neighboring house and damaged a third, chief investigator Dan Given said Wednesday afternoon.
“At this time, we’re not going to release any more information,” Given said.
Earlier Wednesday, the office issued a statement saying investigators ruled out an accidental cause and no charges were currently pending. [. . .]
Investigators have identified six “people of interest,” all family members or friends of the judge. Investigators have also said a canine detected an accelerant in the fire.
The three homes are in Olde Oaks subdivision in northwest Harris County. Damage for all three has been estimated at $900,000.
Officials said Wednesday that Medina family members questioned about the June 28 blaze have been cooperative. The judge’s wife, Francisca Medina, and one of their children were home the night of the fire, officials said.
Investigators have subpoenaed cell phone and financial records of family and friends.
If a charge is filed, it would be arson of a habitation, a second-degree felony that carries a punishment ranging from probation to 20 years in prison, lead investigator Nathan Green said Tuesday. [. . .]
While officials would not discuss possible motives, Green has said a “red flag” was a foreclosure filed on the property in June 2006 that apparently was resolved that December.
The Medinas’ insurance policy had lapsed because premiums weren’t paid, Green has said. Medina was surprised to learn the 5,000-square-foot house in the 3500 block of Highfalls wasn’t covered.
The Medina family moved to Austin after the fire, Green said.
They still owe nearly $2,000 in homeowners association fees, according to Pam Bailey, owner of Chaparrel Management, which manages the Olde Oaks Community Improvement Association.
Bailey said the fees are two years past due.

The house wasn’t insured and Justice Medina didn’t realize it? In an earlier Chronicle article on the fire, Justice Medina, who was appointed to the high court by Govenor Perry in 2004, said he was unaware that investigators had identified six people of interest, including family members and friends.

“I was not aware. … That’s quite startling,” Medina said, later adding that he had “no idea” if he knew anyone who might have set the house on fire.
He then said, “I’m not going to comment further.”

That latter comment is a very good idea.
October 15, 2007 Update: Harris County District Attorney Chuck Rosenthal announces that Justice Medina is not a suspect in the arson investigation:

Texas Supreme Court Justice David Medina is not a suspect in a June arson that destroyed his Spring home, Harris County District Attorney Chuck Rosenthal confirmed Thursday.
The revelation came during a telephone conversation in which Rosenthal alerted the judge that he was being called to testify before the grand jurors as they discuss whether to charge anyone in the June 28 blaze.
“Because in Harris County, we don’t sneak up on people. I said: ‘You are not considered a suspect,’ ” Rosenthal said late Thursday.
