The mother found stabbed to death, along with her two small children, inside their Penns Grove apartment last Wednesday had asked to have the locks changed, according to NJ.com.

A relative of Ruth Reyes Severino, 30, says she made the request after getting a restraining order against her husband. A neighbor says Reyes obtained the restraining order against her husband, Eugenio Severino, after he threatened to kill her. The paperwork had all been submitted, but the locks were never changed.

The apartment complex owner said she could not comment on the claim.

The Salem County Prosecutor’s Office says Severino and her two young children, ages 5 and 2, were found stabbed to death last Wednesday. Eugenio’s body was found in woods in Carneys Point on Wednesday morning.

Authorities continue to investigate the deaths and have not officially labeled the case what relatives believe: Severino killed his family and then took his own life.
