RICHMOND, Va. (WVEC) -- Early next year, the Commonwealth of Virginia will execute Ricky Gray. But the drugs the state plans on using are raising concerns.

Gray was convicted of killing a former Virginia Beach homecoming queen and her family in Richmond on New Year's Day 2006. A court sentenced him to death, likely by lethal injection.

According to our partners at the Virginian-Pilot, the drug combination chosen for the execution includes Midazolam. It's a drug that the state has never used before and has been involved in several botched executions.

Gray's execution date is currently set for January 18. Gray was initially scheduled to be executed in March, but the 4th U.S. Circuit Court of Appeals put his execution on hold while he appealed to the U.S. Supreme Court. The high court declined to hear his case in October.
