No criminal charges have been filed in any of three incidents that caused the deaths of four people in Delaware County earlier this month.

Investigations into all four deaths remain open.

The first accident took place Aug. 1 when the driver of a semi-truck ran a red light and hit a Honda CRV as it was turning through the intersection of U.S. 36 and State Route 521. The occupants of the CRV, Anthony M. Marsello, 82, and his wife, Nancy J. Marsello, 78, residents of 22 Snowberry Drive, Delaware, died as a result of the crash.

The driver of the truck, Jeremy Sloan, 33, of Sugarcreek, Ohio, has not been charged in connection with the crash. Delaware police say an investigation is continuing.

Police said Friday that they are reviewing data from the truck’s onboard computer to reconstruct the accident.

On Aug. 2, 19-year-old Morgan Montgomery, of Willunga, Australia, was visiting Alum Creek Lake as part of a church camp trip and fell into the lake while water skiing and was hit by a boat operated by Andrew Lehman of Westerville.

Investigators searched for Montgomery’s body after the accident and again on Aug. 3. Her body was finally recovered Aug. 3 north of the beach and south of the marina.

Ohio Department of Natural Resources staff said no charges have been filed in the Alum Creek case.

The county’s fourth death this month occurred on Aug. 4 when a westbound SUV driven by Marilyn Fowler, 60, of 33 Downing Road, Delaware, turned in front of a motorcycle on London Road. Keith Estep, 29, of 16 Hedgerow Lane, Delaware, was killed when his eastbound motorcycle collided with Fowler’s SUV.

Police said Estep was traveling at 50 miles per hour, 15 miles over the posted speed.

No charges have been filed by Delaware police in that case either, a spokesman said Friday.
