The father of a college student accused of randomly killing a couple and biting the dead husband's face says his son's organs are malfunctioning.

Dr. Wade Harrouff told The Palm Beach Post (http://pbpo.st/2bgtgwj ) that his 19-year-old son, Austin Harrouff, who is in critical but stable condition, has a malfunctioning liver, fluid in his lungs and a bleeding esophagus. The South Florida dentist said the hospital is doing an MRI on Wednesday.

Martin County Sheriff William Snyder has said Austin Harrouff may have ingested chemicals from the garage of John Stevens and Michelle Mishcon during the Aug. 15 stabbings, which also wounded their neighbor. The sheriff says the former high school football player and wrestler will be charged with murder once he's out of the hospital.
