A Suffolk jury spent about 6 1⁄2 hours deliberating Wednesday about whether a Sound Beach contractor was driving drunk and knew he had hit and killed a neighbor who was walking home.

Deliberations will resume Thursday in Central Islip in the trial of Christopher Campbell, 37, who is charged with vehicular manslaughter, leaving the scene of a fatal accident and other crimes in the Oct. 18, 2014 death of Tracy Mangino, 40.

Suffolk prosecutors said Campbell got drunk at a series of bars before driving home in a box truck, which hit and killed Mangino while she was walking home from Napper Tandy’s, the same Miller Place bar Campbell was last at.

But Campbell’s attorneys argued that he was the victim of an overzealous prosecution that relied on innuendo and speculation in an attempt to inflate a mere accident into crimes.

A home security video of the impact showed Mangino, who was drunk, suddenly bending down into the road to pick something up just as Campbell’s truck approached.

Campbell was initially charged only with leaving the scene of a fatal accident.

As his trial on that charge was about to begin last year, he was charged with vehicular manslaughter and driving while intoxicated, based on witness accounts of people who say they saw him drinking that night.
