A former Charleston man who served prison time for a pair of stabbing sprees in the 1970s was convicted of murder in a White Plains, N.Y., courtroom Thursday.

Lucius Crawford, 61, was found guilty of second-degree murder in the 2012 killing of his girlfriend, but jurors continued deliberating in the death of a Yonkers prostitute stabbed almost two decades earlier, according to The Journal News newspaper.

The trial began May 12, according to court records.

Crawford went on trial in the fatal stabbings of two of the three women he's accused of killing in New York, according to The Associated Press.

Crawford was arrested on Dec. 4, 2012, accused of a pair of cold-case homicides and the killing of his 41-year-old girlfriend, Tonya Simmons, who was found stabbed to death in his bed at his Mount Vernon apartment, according to police.

Jurors still have to decide on the charge against Crawford in the alleged 1993 killing of Laronda Shealy.

Crawford moved to New York after he was released from prison in South Carolina in 1991 following two non-fatal stabbing sprees in the Charleston area.

Less than a year after his release, the 24-year-old ex-con was back at it, attacking and stabbing five women over a five-day period in April 1977, police said.

In June 1977, Crawford pleaded guilty in four of the attacks, and a judge handed him a 24-year prison sentence, court records show.
