CASTLE ROCK, Colo. -- A teenager who was text messaging when he lost control of his vehicle and struck and killed a cyclist has pleaded guilty to careless driving causing death.

Douglas County sheriff's Lt. Alan Stanton said that Jim R. Price, 63, was riding his bicycle in a bicycle path Nov. 23 when he was hit by the teen's car near Wildcat Reserve Parkway and Summit View.

District attorney spokeswoman Kathleen Walsh said the 17-year-old was sentenced to four years probation. He will not be allowed to operate a motor vehicle or possess a cell phone during that time.

The teen will be in home detention, be required to wear an ankle bracelet, and serve nine days in jail.

The teen must also perform 300 hours of community service, pay $2,600 in fines and court costs.
