SPRINGFIELD, Ill. (AP) — The Latest on Drew Peterson's murder conviction in the death of his third wife (all times local):

1:45 p.m.

An attorney for Drew Peterson says he'll likely appeal an Illinois Supreme Court ruling upholding the former suburban Chicago police officer's murder conviction in the death of his third wife.

The Illinois Supreme Court on Thursday ruled that hearsay statements by Peterson's third and fourth wives were properly used against him. Kathleen Savio's 2004 death was initially ruled accidental but was reclassified a homicide in 2007 after Peterson's fourth wife, Stacy Peterson, disappeared.

Peterson's attorney, Steven A. Greenberg, said in a statement that an appeal to the U.S. Supreme Court is likely. He says the Illinois Supreme Court decision shows that the state has one set of laws for the general public and another for Peterson.

Illinois adopted a hearsay law in 2008 tailored to Peterson's case, dubbed "Drew's Law," which assisted in making some of the evidence admissible.

The prosecutor who convicted former suburban Chicago police officer Drew Peterson of first-degree murder in the death of his third wife calls an Illinois Supreme Court ruling upholding the verdict the "ultimate vindication."

The Illinois Supreme Court ruled Thursday that hearsay statements by Peterson's third and fourth wives were properly used against him.

Peterson was convicted of killing his third wife, Kathleen Savio. Her 2004 death was initially ruled accidental but was reclassified a homicide in 2007 after Peterson's fourth wife, Stacy Peterson, disappeared.

Will County State's Attorney James Glasgow says the ruling means the court recognizes that he properly used a state law passed in 2008 that allowed him to use statements that Savio and Stacy Peterson made to others.

Glasgow says Peterson believed that friends and family of the women could never testify about how Peterson told them he could kill them and make their deaths look accidental.

The Illinois Supreme Court says hearsay statements by Drew Peterson's third and fourth wives were properly used against him in a murder conviction.

The high court on Thursday upheld the former Chicago-area police officer's murder conviction in the death of his third wife, Kathleen Savio. Her 2004 death was initially ruled accidental but was reclassified a homicide in 2007 after Peterson's fourth wife, Stacy Peterson, disappeared.

The court said statements that Savio and Stacy Peterson made to others could be used under a theory of "forfeiture by wrongdoing."

The justices found it "reasonable" for prosecutors to contend Peterson killed Savio and Stacy Peterson to keep them from testifying against him. Officials presume Stacy Peterson is dead but she's never been located and no one has been charged in her disappearance.

The Illinois Supreme Court has upheld the murder conviction of former police officer Drew Peterson in the death of his third wife.

The high court ruled unanimously in an opinion released Thursday. It said that the use of hearsay testimony in Peterson's 2012 trial for the death of Kathleen Savio did not violate Peterson's cross-examination rights.

Savio's body was found in a bathtub in 2004. The death was initially ruled accidental, but the case was reopened after the 2007 disappearance of Peterson's fourth wife, Stacy Peterson.

Statements Stacy Peterson allegedly made to her pastor and others were used against Drew Peterson in the Savio case.

The 63-year-old Peterson was convicted last year of plotting to kill the prosecutor in the Savio case.

The Illinois Supreme Court is scheduled to rule on whether former Chicago-area police officer Drew Peterson was properly convicted of murder in the death of his third wife.

The court announced it would release its opinion Thursday on Peterson's appeal of his 2012 conviction in the death of Kathleen Savio.

He claims the use of hearsay testimony at his trial violated his constitutional right to confront his accusers.

Savio's 2004 death was initially ruled accidental, but the case was reopened after the 2007 disappearance of Peterson's fourth wife, Stacy Peterson.

Statements Stacy Peterson allegedly made to others were used against Drew Peterson at his trial. He's serving 38 years for Savio's death.

He's also serving 40 years for allegedly plotting to kill the prosecutor who put him behind bars.
