Oxygen’s Serial Killer Week is set from April 10-18. During this time, not only will ongoing series like Snapped and Mark Of A Serial Killer get new episodes, but the network is releasing new specials on infamous killers like Joel Rifkin, Bruce McArthur, Joanne Dennehy, and Dorothea Puente.

Murders At The Boarding House will focus on Puente, a landlady who schemed to rob her boarders of their Social Security checks and then kill them. The A.V. Club is premiering the trailer for the special, which explores explore how an elderly Puente came under suspicion when human remains were discovered in the backyard of her Sacramento, California boarding house.

It all started when the police received a missing person’s complaint from a concerned social worker, prompting Detective John Cabrera to go to Puente’s boarding house.
