The death of a Bronx woman — struck in the head and killed with a kettlebell — sent her boyfriend on a downward spiral of grief that included a string of arrests, desperate attempts to get him help and finally ending with him being stabbed to death on the street weeks later in a tussle with a homeless man over a box to sleep in. The tragic confrontation came at the end of a weeks-long spiral. An overwhelmed Juan Boria, 51, had continued living among blood spatter in the Throggs Neck house where Jacklyn Timinski was attacked on Sept. 8 and was not taking medication for his bipolar disorder, according to his heartbroken son, Joshua Boria.

This is the first part of a two-part series on a pair of seemingly unrelated killings in the Bronx the Daily News has found share a common – and tragic – thread. Read the other part here. According to police Juan Boria was arrested four times, on charges including assault, harassment, and criminal mischief, during a 10-day stretch in the six weeks between Timinski’s death and his own murder on Oct. 26. “He was a danger to himself and to the people around him,” said Joshua Boria, who was struggling to get his dad help during that time. “He was grieving. He was on a suicide mission … He was going outside starting fights and he was looking to get hurt.” Juan “Joey” Boria A 59-year-old neighbor named Barbara said Juan Boria had been acting more and more erratic since his girlfriend was killed — and had even made a chilling promise. “He kept saying he was going to make the news,” said Barbara. “He was going to have the news here.” The spiral, by many accounts, was touched off by another tragedy — the brutal death of Timinski, 37, whose last months alive were full of upheaval. After her 18-year-old daughter Olivia Rios died of suicide on Jan. 31, the grieving mom lost the will to live, her friends say. “She was so depressed, so upset about what happened to her daughter that she just didn’t care about her life anymore,” said one friend, a woman who did not provide her name. Jacklyn Timinski (front) is pictured with her daughter, Olivia Rios, in an undated photo. On Sept. 8, Timinski had returned to the couple’s home on Shore Drive with Benjamin Lozovsky. A law enforcement source said Timinski brought Lozovsky home to do drugs with him. There, police say, Lozovsky used a kettle bell to bludgeon her. Timinski clung to life for another week before succumbing to her injuries on Sept. 15. Lozovsky, once a successful celebrity photographer, was arrested at the scene and is now charged with murder, manslaughter and criminal possession of a weapon.

On Oct. 11, Juan Boria arrived at the house on Shore Drive near Barkley Ave., which originally belonged to Timinski’s late grandfather, to find it boarded up in the wake of Timinski’s death. He ripped the boards off and set them on fire in the front yard of the home, according to shocked neighbors. Boria was arrested that day for arson, burglary and criminal trespass. “He started the fire and then he sat in the chair with the hose thinking he had it under control and the fire department came,” said Barbara. “It scared the hell out of me. A good gust of wind, these houses are gone.” Firefighters work to put out a fire Juan Boria allegedly set on his lawn on Oct. 10, 2024. Boria is pictured at far right using a hose on the fire.

He was planting a cluster of orange marigolds on the front lawn near a memorial he created for his slain girlfriend. “We were in the process of trying to get him some mental health help,” Juan Boria’s son said. “Same thing that happened with the girlfriend that died. He was fighting a battle to try to get her some mental health help and he really felt like the system failed him.” Flowers neighbors say Juan Boria planted in his yard on Oct. 26, 2024, the last time they saw him alive. (Rebecca White for New York Daily News) Juan Boria agreed to go to Bellevue Hospital for psychiatric evaluation the week before he died, his family says, but was released, to their dismay, just three days before he was killed. “We asked them to keep him because he was dangerous,” Joshua Boria said. Just three days after being released from Bellevue, Boria met a homeless man who was mourning his own loss, said that suspect’s family. Juan Boria was stabbed in the abdomen in the bustling commercial area of the Bronx called the Hub in Melrose about 7:30 p.m. Oct. 26. Medics took him to Lincoln Hospital but he couldn’t be saved.

(Theodore Parisienne for New York Daily News) The day after his slaying, police arrested Robert Brent, 52, charging him with Juan Boria’s killing. A law enforcement source said the men had begun to argue after Boria tried to take the box Brent was sleeping in on E. 149th St. and Third Ave. Brent and Juan Boria were familiar faces to the homeless people, drug users and others who hang out at the Hub. Brent attended a nearby methadone clinic and voluntarily swept and cleaned the streets in the area. “They [were] both equally loved,” a woman who hangs out in the area who gave her name as Asia, 63, said. “We all a family. We here every day together. They both was good guys.” Juan Boria was knifed in the abdomen during a clash on E. 149th St. and Third Ave. in the Bronx on Saturday, Oct. 26, 2024. (Theodore Parisienne for New York Daily News) On the day of the stabbing Juan Boria was relentlessly goading Brent as he mourned his mother, multiple people who frequent the area and interacted with both men that day told The News. “All day [Brent] kept telling Joey, ‘Leave me alone’,” said Schlena Pollard. Brent’s mother, who he visited frequently in Far Rockaway, Queens, had died two weeks earlier. Her funeral was scheduled for five days after Brent’s arrest, said his brother, Reginald Brent. “Even though he was struggling with drugs and homelessness, that was not his M.O. to murder anybody. That’s the furthest thing from his mind,” said Reginald Brent, who added that his brother had been in a shelter for two to three years. “He was never a violent person. He’s never been arrested for violence. It was always drugs.” Robert Brent (pictured) was charged with killing Juan Boria. Police sources said Robert Brent had nine past arrests for charges including drug possession, weapon possession and robbery. Robert Brent is charged with murder, manslaughter and weapon possession for Juan Boria’s stabbing but due to a hospitalization after his arrest still has not been arraigned in Bronx Criminal Court. The area of ground below this elevated bench is where friends of Robert Brent say he used to sleep on a cardboard box near near E. 148th St. and Third Ave. in the Bronx. Friends say he was lying here when first approached by Juan Boria the day of Boria’s death.

Boria’s son said he wishes authorities would have done more to help his father. “Them seeing that, coming to check on a person and their mental health, they see someone is not in their right mind when there’s still a pool of blood there 30 days later,” said Joshua Boria. “He was crying out for help in a very aggressive way,” he added. “His whole thing was if nobody’s going to listen to me, you have to make noise. You have to be seen.”
