Michael Graczyk reports for AP:

A serial killer was put to death Thursday in Texas after the U.S. Supreme Court rejected his lawyers' demand that the state release information about where it gets its lethal injection drug.

Tommy Lynn Sells, 49, was the first inmate to be injected with a dose of newly replenished pentobarbital that Texas prison officials obtained to replace an expired supply of the powerful sedative.

Sells declined to give a statement. As the drug began flowing into his arms inside the death chamber in Huntsville, Sells took a few breaths, his eyes closed and he began to snore. After less than a minute, he stopped moving. He was pronounced dead 13 minutes later, at 6:27 p.m. CDT.

For all the wailing and gnashing of teeth over the undisclosed sources, we see once again that the single-drug method with pentobarbital is the way to go for lethal injection.  Another murderer snores his way to eternity and removal to a higher court.

To the extent that anyone is faced with a potentially painful execution by the substitution of other drugs, the blame for that falls squarely on the shoulders of those obstructing the supply.  For a manufacturer to restrict resale of its product should be illegal.  It is a restraint of trade.  Eliminating the barriers to supply is the solution.

The Supreme Court orders are here and here.  No dissent is noted.
