Kevin Scott, the 18-year-old Northwest Washington man convicted of murdering an elderly Silver Spring Woman in May, was sentenced yesterday to life imprisonment.

Scott was also sentenced by Montgomery County Circuit Court Judge Stanley Frosh to a consecutive 10-year sentence for use of a handgun in the course of a felony, the judge said. Scott must be considered for parole after serving 15 years.

Scott was convicted of first degree murder in the shooting death of Rose Blanco, 68, of 2301 East-West Hwy. Blanco had been shot in the back of the head in her home while washing a front window.

Scott was also convicted of armed robbery and housebreaking in the Blanco case and received a total sentence of 30 years on those charges to be served concurrently with the life imprisonment sentence.

Scott, who lived at 1933 Tulip St. NW., came from a well-to-do family and was described a "a nice young man" by neighbors after his arrest. School authorities described him as something of a misfit who was failing many of his courses.

He goes on trial next week on charges of assault with intent to murder in the shooting of Louise McKenna, 61, of 2007 Grace Church Rd., Silver Spring. He is also charged with housebreaking, robbery and use of a handgun in that case.
