Jury selection is scheduled to begin Monday in the trial of a man accused of fatally strangling a fellow patient at a Maryland state mental hospital, reports the Associated Press.

El Soundani El-Wahhabi, also known as Saladin Taylor, is charged with first- and second-degree murder in the 2010 death of 45-year-old Susan Sachs at Clifton T. Perkins State hospital in Jessup, Md.

According to court documents, El-Wahhabi slipped into Sachs’s, kissed her and strangled her to death with shoelaces.

Sachs and El-Wahhabi lived in a medium-security area of the forensic hospital. El-Wahhabi lived three doors down from Sachs, and the two reportedly were friends, according to police.

Sachs had been committed to Perkins after fatally stabbing her landlord, 71-year-old Joyce Hadl, in 2004.

El-Wahhabi was sent to the hospital after he killed someone in Baltimore in the 1990s, according to court records.

El-Wahhabi’s trial in Sachs’s murder begins this week in Howard County Circuit Court.
