BALTIMORE, Md. — A Maryland commission has asked the courts to discipline or fine a former prosecutor for allegedly withholding evidence in a double slaying nearly 40 years ago.

The Baltimore Sun reports that the Maryland Attorney Grievance Commission is seeking action against former Harford County State’s Attorney Joseph Cassilly.

On Memorial Day 1981, police found Diane Becker, 21, stabbed and beaten to death with a bottle in her camper home in an Abingdon RV park. Police found her boyfriend, Joseph Hudson, a popular local disc jockey, shot to death a few miles away.

Cassilly twice prosecuted John Norman Huffington for the murders, but he was twice granted new trials. In 2017, the two men reached a plea deal and Huffington was released after serving 32 years in prison.

The Attorney Grievance Commission, which investigates complaints against attorneys, alleges Cassilly intentionally suppressed reports and letters that found fault with a portion of the forensic evidence.

Cassilly, who retired in 2019, downplayed the significance of these records.

“It was irrelevant and did not bear on the overwhelming evidence against this guy,” Cassilly told the Sun.

In November 2018, Huffington filed a complaint against Cassilly to launch the commission’s investigation.

“It’s about the truth, and it’s about maintaining the integrity of our system,” Huffington said.
