In a new incident among a spate of case-related violent attacks on lawyers in recent weeks, a Minnesota man has been charged with attempted murder after allegedly stabbing his ex-wife's attorney a dozen times in her law office on Friday.

Terri Ann Melcher, 54, was alone in her Fridley, Minn., office at the time and called 911 after the suspect, Sheikh Nyane, departed, reports KARE 11. She is in critical but stable condition and is expected to survive.

Nyane, who reportedly turned himself in and confessed to authorities on Friday, was apparently enraged by losing custody of his child.

Relying on information from police, the station reports that Nyane's attorney called Melcher's office to warn her that his client might become violent. However, the message wasn't received until today, when her law office opened for business.
