A Dorchester teen was committed to the Department of Youth Services today following his admission to a stabbing spree last year that left his mother near death, three other female relatives with stab wounds, and two others with serious injuries.

DARIUS YOUNG (D.O.B. 2/25/93) pleaded guilty on Jan. 19 to five counts of armed assault with intent to murder and seven counts of assault and battery with a dangerous weapon for incidents in his Dorchester home on Feb. 3, 2010, and at his then-girlfriend’s Revere home on Feb. 7, 2010. Suffolk prosecutors indicted Young as a youthful offender, exposing him to the same penalties as an adult.

Assistant District Attorney Lynn Feigenbaum of Suffolk County District Attorney Daniel F. Conley’s Major Felony Bureau recommended that Young be sentenced to a term of seven to nine years in state prison plus 10 years of probation upon his release.

Boston Juvenile Court Judge Stephen Limon today ordered Young committed to DYS until the age of 21, placed him on probation until the age of 25, imposed a seven- to nine-year prison term that he ordered suspended until Young’s 25th birthday, and a two-and-a-half year jail term that was also suspended for two and a half years.

If Young abides by the set of conditions Limon also imposed, he will not serve prison time. If he violates the court’s orders, he could be re-sentenced to up to 20 years behind bars.

The conditions of Young’s release, Limon ordered, are that he provide a DNA sample for the state’s database, obey all local and federal laws, report to the Department of Probation within 48 hours of his release and regularly thereafter, allow his probation officer to visit him without notice, not leave Massachusetts without notifying his probation officer, remain drug- and alcohol-free, submit to random drug and alcohol testing, seek and comply with all mental health treatment, take any medications as prescribed by medical professionals, stay away from the victims in the case, and abide by any restraining orders.

Had the case proceeded to trial, Feigenbaum would have introduced evidence and testimony to prove that Young stabbed his mother, then 51, in the throat repeatedly as she lay in bed on Feb. 3. He then stabbed three other female relatives between the ages of 6 and 29 before leaving the home and fleeing to Revere.

Feigenbaum would also have introduced evidence to show that Young went to a girlfriend’s home and stayed until her aunt told him to leave in the early morning hours of Feb. 7. The evidence would have shown that he stabbed her in the chest and neck and kicked the girlfriend in the face before fleeing that residence as well.

Revere Police captured the youth on Feb. 9 after a search by Boston, Revere, and State police. After a foot pursuit through areas of Revere, officers located him in a recycling bin near the intersection of Ridge Road and Tudor Street. He was taken into custody after a brief struggle and held on a total of $1.6 million cash bail at subsequent arraignments in Dorchester and Chelsea district courts.

Katie Conner was the DA’s assigned victim-witness advocate. Young was represented by attorney Ziyad Hopkins.
