BIDDEFORD (AP) — A grand jury has indicted a Biddeford man authorities say was drunk when his pickup truck struck a family riding their bicycles, killing the dad.

The Portland Press Herald (http://bit.ly/17cqShJ ) reported that David Labonte was indicted Thursday on charges including manslaughter and drunken driving.

Police said the 56-year-old Labonte drove into the family on Aug. 2 while they were riding on the sidewalk. Jamerico Elliott was killed, and his 15-month-old son, in a seat on his dad’s bike, was severely hurt. The boy’s mother, Melodie Brennan, suffered less serious injuries.

Police said Labonte’s blood-alcohol content was about twice the legal threshold for driving. Because of prior drunken driving convictions, he was not allowed to drive with alcohol in his system.

Labonte said an asthma-induced coughing fit caused him to pass out.
