Authorities say an elderly couple who died in an apparent murder-suicide at their northern New Jersey home had a history of domestic incidents.

Elmwood Park police tell The Record (http://bit.ly/1DHkB2D ) that since 2012, officers had responded to three calls at the home of 100-year-old Michael Juskin and his 88-year-old wife, Rosalia. Authorities believe Michael Juskin killed his wife with an ax as she slept late Sunday, then killed himself in the bathroom with a knife.

Family members say Michael Juskin suffered from dementia.

In March 2012, police responding to a 911 call found him to be unstable and took him to a hospital for evaluation. Another call came in September 2013, when Rosalia Juskin claimed he was harassing her.

The third call came Jan. 13, when Rosalia Juskin said her husband had locked her in the basement in his confusion.
