A Maryland man is behind bars after authorities say he is responsible for his wife’s cold case murder over two decades ago. 

Dwight "DJ" Rust Jr. was taken into custody Tuesday on charges stemming from the 2002 death of Michelle Rust, the Baltimore County Police Department said Dodge Caravan was discovered with the key broken off in the driver’s side door later that day by her father-in-law near Zion Avenue and Clyde Avenue, but Michelle Rust was never found.

Members of her family insisted she "was a dedicated mother and daughter" and "would not have disappeared on her own," leading investigators to determine she was a victim of foul play, police said.

The case ran cold for 24 years, until authorities announced Dwight Rust had been arrested and charged with first-degree murder in Baltimore County on Tuesday. 

Authorities did not provide additional details regarding what led them to Dwight Rust.

He was subsequently booked into the Baltimore County Detention Center, where he is being held without bail. 

The Baltimore County Police Department did not immediately respond to Fox News Digital’s request for comment.
