Man convicted of psychiatrist stabbing sentenced to life

A Delaware man convicted of fatally stabbing a psychiatrist who once treated him has been sentenced to life in prison.

Christopher Frick pleaded guilty but mentally ill in September in the killing of 55-year-old Caroline Ekong. The Wilmington News Journal reports ( ) Frick was sentenced Friday to life in prison, plus 25 years.

Authorities have said he plotted Ekong's death for at least a year. They say Frick was angry that Ekong refused to let him leave a psychiatric facility.

Frick apologized Friday and said he wishes he could take it back. Three mental health experts concluded that Frick suffers from a host of mental disorders. His plea means he will receive psychiatric treatment while incarcerated.

Ekong's daughter, Koko Ekong, said Friday that her mother was a "woman of integrity."
