The family of Susan Ledyard, a Delaware County, Pennsylvania, high school teacher whose body was found in a river seven years ago, is offering a reward for information leading to an arrest in her unsolved murder.

Ledyard’s parents, siblings and loved ones have teamed up with Delaware Crime Stoppers to offer a $50,000 reward.

Ledyard’s body was found by a construction worker in the Brandywine River in Wilmington, Delaware, on July 23, 2019. The state’s forensic’s team determined Ledyard died from blunt force trauma to the head and drowned. Her manner of death was ruled a homicide.

As reported by CBS News Philadelphia in 2020, evidence showed that there was a four-hour timeframe between 3 a.m. and 7 a.m. that morning where Ledyard’s whereabouts remain unknown. Her car was seen leaving her driveway at 3:02 a.m. and her Fitbit confirmed she was still alive at 7 a.m. Her body was discovered in the river about 40 minutes later. Her car was located three miles away from where her body was found.

Through a press release from the state police, love ones said that they are desperate to get justice for her.

“We miss Susan every day,” the Morrissey family said. “We need everyone to help us spread the word about her case to generate tips.”

“Someone is waking up every day and going to sleep every night knowing they have taken her life and shattered her family,” Meg Morrissey-Heinicke, Susan’s sister, told CBS News Philadelphia in 2019.
