BOSTON — A lawyer for a Massachusetts man fighting extradition to Scotland where he faces attempted murder charges for allegedly poisoning a fellow college student’s wine told a panel of judges that her client should not be sent overseas because of his mental illness.

The lawyer for 22-year-old Alexander Hilton of Princeton told three judges from the 1st U.S. Circuit Court of Appeals in Boston on Wednesday that Hilton takes several medications for numerous psychological conditions and is a suicide risk.

The Telegram & Gazette reports that Hilton is appealing a lower court’s ruling that he should be returned to Scotland.

The appeals court did not immediately rule.

Scottish authorities say Hilton was studying at the University of St. Andrews in March 2011 when he spiked another American’s wine with methanol, making him severely ill.
