 But it's still not clear what sparked the murder-suicide late Sunday in Elmwood Park. 
 
 Bergen County Prosecutor John Molinelli says there was a "history of domestic issues" between Michael Juskin and his 88-year-old wife, Rosalia. But he said a motive for the attack remains under investigation. 
 
 Police officers found the couple in their Spruce Street home after relative — who was not in the home — called authorities. The deaths were made public Monday. 
 
 Authorities do not believe anyone else was in the home when the attack occurred. 
 
 Neighbors told The Record newspaper that they often saw the couple out and about — Michael Juskin walking a dog and his wife tending to her garden — but said they kept to themselves. 
 
 Barbara Szczecina, 65, who lives down the block, said she saw Rosalia sitting on her front porch around 10 a.m. Saturday. 
 
 "She used to be in her garden all the time," Szczecina said. "They were always together, putzing around outside." 
 
 Family members who were at the home on Monday declined to comment on the deaths. ||||| A 100-year-old Elmwood Park man whose family said he suffered from dementia killed his 88-year-old wife with an ax as she slept, before taking his own life with a knife, according to authorities, becoming one of the oldest people ever accused of homicide.

Update: Elmwood Park police called to home of couple in murder-suicide three times TARIQ ZEHAWI / STAFF PHOTOGRAPHER Bergen County Sheriff's Department and Prosecutor's Office on the scene at a home on Spruce Street Monday morning. Michael and Rosalia Juskin had a “history of domestic issues,” Bergen County Prosecutor John L. Molinelli said in a tweet on Monday evening. He said authorities had yet to determine a motive for the murder-suicide, which he said had taken place sometime late Sunday. The bodies were found early Monday after a relative, who was not at the home at the time of the violence, called police, authorities said. Molinelli said Michael Juskin committed suicide in a bathroom at the couple’s Spruce Street home after killing his wife. He did not provide further details. Related: Domestic violence a hidden problem among the elderly Elmwood Park Police Chief Michael Foligno said that the exact time of death was unknown and that he did not believe anyone else was in the two-family house when the killings happened. He referred all other questions to the Prosecutor’s Office. Neighbors said they often saw the couple out and about — Michael walking his dog and Rosalia tending her garden. A family member who insisted on anony­mity said Michael had been suffering from dementia, a condition that affects the brain and is sometimes related to aging. “Sometimes he was lucid and sometimes he wasn’t,” the family member said. Mobile users, click here for video The Juskins often “kept to themselves,” said one neighbor, Teresa Communicates. She said she had conversations with Rosalia as she worked in her garden but that Michael “wasn’t the type to converse.” 
 
 “It really is sad — and shocking, to be honest,” Communicates said. 
 
 Another neighbor, Dorota Biskup, 42, said police had been to the Juskin home a few times in recent years. Foligno confirmed that police had been there on several occasions over the years but did not provide details. Police reports of those incidents were unavailable Monday afternoon. Molinelli did not provide details about the couple’s domestic issues. 
 
 The Juskins had been living part time in a condominium complex in Gulfport, Fla., until they sold it a little more than a year ago, former neighbors from the complex said. 
 
 One of them, Carole Lynch, said Rosalia told her that Michael was “not well” but did not tell her specifically what was wrong with him. Lynch said Michael “didn’t talk much” but that she sometimes heard him “hollering through the door” as she passed the Juskins’ apartment. 
 
 More than a year ago, the Juskins moved to the east coast of Florida to be near a daughter, Lynch said. Rosalia wanted to live in Florida full time but told her that Michael wanted to keep their home in New Jersey, Lynch said. She remembered Rosalia as “a very sweet lady.” 
 
 One of the Juskins’ neighbors in Elmwood Park, Barbara Szczecina, said she last saw Rosalia sitting on her front porch at 10 a.m. Saturday. 
 
 “She used to be in her garden all the time,” said Szczecina, 65. “They were always together, putzing around outside.” 
 
 Another neighbor, Karen Bionda, 67, said she remembered seeing Michael walking his dog around the neighborhood. “I didn’t think stuff like this happened in nice neighborhoods, huh?” she said. “This is just too close to home.” 
 
 Family members who stood outside the Juskins’ home on Monday declined to comment. A woman who later answered the phone at a relative’s home said the family was too distraught to talk. 
 
 It could not be verified on Monday whether anyone older than Michael Juskin ever has been accused of committing a homicide. 
 
 In 2011, a 96-year-old woman became the oldest person ever charged with murder in Florida in the fatal shooting of her 53-year-old nephew. Authorities dropped the charges two years later after the woman was found to be not mentally competent to stand trial. 
 
 Last year, a Massachusetts woman who strangled her nursing home roommate in 2009 was ruled incompetent to stand trial at age 102. Authorities said the woman, who had a longstanding diagnosis of dementia, was the oldest murder defendant in the state’s history. The woman, who was committed to a psychiatric hospital, was 98 at the time of the killing.

– A century-old New Jersey man ended his long life in a horrific fashion on Sunday, killing his sleeping wife with an ax before taking his own life, according to a prosecutor in Bergen County, NJ. The bodies of Elmwood Park residents Michael Juskin and his wife Rosalia, 88, were found after a relative (who wasn't there at the time of the apparent murder-suicide) called police, the AP reports. The prosecutor says Juskin appears to have killed himself in a bathroom with a knife after killing his wife, and while the motive isn't known yet, the couple had a "history of domestic issues," the Bergen Dispatch reports. A family member tells the Record that Juskin had dementia and "sometimes he was lucid and sometimes he wasn't." A former neighbor tells the newspaper that Rosalia, who could often be seen tending her garden, was a "very sweet lady." Police had been called to the house several times in the last few years, neighbors say. The Record also notes that Juskin may be the oldest person on record to be accused of homicide; a 102-year-old Massachusetts woman accused of killing her nursing home roommate when she was 98 was ruled unfit for trial last year. (A doctor in Indiana killed his wife and himself a few hours after their wedding.)
