WELLESLEY (AP) -- A grand jury has declined to indict a truck driver police say struck and killed a cyclist in Wellesley last summer and then drove from the scene.

Police say 51-year-old Dana McCoomb, of Wareham, was behind the wheel of a truck that struck 41-year-old Alexander Motsenigos on Aug. 24.

Police and prosecutors had sought various charges against McCoomb -- who has a lengthy driving record including 19 license suspensions -- including motor vehicle homicide.

Authorities announced Monday that the grand jury failed to indict.

A grand jury is not required to explain its decision, but Wellesley Police Chief Terrence Cunningham tells The Boston Globe he's "disappointed."

A lawyer for McCoomb said he was pleased with the decision.

Motsenigos' family is going forward with a lawsuit against McCoomb.
