Jeffrey Jastrzembski, 54, had a blood-alcohol level of nearly 2½ times the legal limit when he turned into two women swimming near the dock Aug. 12, near the Albany Avenue Bridge, according to the charges.
One of the women was able to dive under the boat and escape harm.
Norma Michaels, 79, of Ventnor, was struck by a propeller and killed.
Many patrons at the nearby Wonder Bar saw the incident, yelling for Jastrzembski to slow down.
Instead, he abruptly turned into the two women swimming near the dock, according to the charges.
Several people said they saw him discarding empty bottles.
"As he parked, he tossed items in the water that appeared to be cans or bottles," Alan Houser told BreakingAC at the time. "(Jastzembski) immediately ran off of his boat and around the front of the house he parked behind."
Video surveillance from the bar captured the fatal crash.
An investigation led to his arrest in January for aggravated manslaughter.
"He is completely remorseful," his attorney said during his detention hearing shortly after he was jailed.. "This has devastated his life."
Charles Nugent Jr. successfully argued for Jastzembski's release at the time, citing his lack of criminal history and that his client wasn't a flight risk.
