A 100-year-old New Jersey man murdered his sleeping 88-year-old wife with an axe, then fatally slit his own wrists, according to authorities.

Bergen County prosecutors say Michael Juskin committed the aforementioned crime late Sunday night, in his home in Elmwood Park. His wife, Rosalia, was murdered in her bed; Juskin was found dead in his bathroom.

The Juskins were reportedly no strangers to visits from the Elmwood Park Police Department, and the Times reports that cops had been called to the house three times since 2012. At least one call claimed Juskin was demonstrating "erratic, dementia-type behavior"; another was over a domestic argument that did not apparently result in violence.

A neighbor told the paper that Juskin repeatedly told her he needed to get a divorce. "He was very unhappy; he thought his wife was taking his pension money,” Alejandra Gonzalez, 24, said. “He might have thought she was cheating on him.”

Police blamed the incident on the couple's age and deteriorating mental states. “Basically, you have two elderly people sort of starting to lose their faculties, not any type of criminal behavior,” Chief Michael Foligno told the Times. "There’s nothing else you could have done or foreseen that a murder would happen."

Sunday's murder-suicide is the third in the area in recent months. In February, Bergen County resident Michael Tabacchi strangled and stabbed his wife to death before killing himself. And last month the September deaths of Somerset County residents John and Joyce Sheridan were ruled a murder-suicide, with officials concluding that John Sheridan stabbed his wife to death and set their bedroom on fire.

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
