In an impassioned note posted to Facebook, the estranged wife of the man who fatally shot an NYPD officer in the Bronx last Friday, argued he should never have been allowed on the streets. “This is something that should have been prevented and could have been prevented time and time again," Tia Giattino wrote in her note. "Manny should never have been on the street in the condition he was in."

Manuel Rosales's deadly encounter with the NYPD was initially reported as an armed robbery gone wrong, but since then revelations regarding his mental health state have recast the incident as suicide by cop. According to the Times, Rosales had called a suicide hotline years ago and mentioned wanting to shoot at a Long Island station house so that officers would return fire and kill him.

Last Thursday evening, Rosales, 35, reportedly wrote on Facebook "This nightmare is coming to an end...goodbye." Hours later, he was locked in a shootout with multiple NYPD officers near 1575 Noble Avenue. Rosales fatally shot Sgt. Paul Tuozzolo, 41, in the head and struck Sgt. Emmanuel Kwo, 30, multiple times. Kwo was rushed to Jacobi Hospital where he was treated and later released. The Daily News reports that Rosales was fatally shot by Officer Elwin Ramirez, a 25-year-old NYPD recruit who had been out on field training.

"As hurt and distraught and grief stricken as I am by this end, I can't stop also thinking of that officer and his wife and children ... I'm devastated," Giattino wrote in her Facebook note. Speaking at Jacobi Hospital Saturday, Mayor de Blasio ordered that flags be lowered to half-staff across New York City in memory of Tuozzolo, and also pledged "years and years" of support for the Sergeant's grieving family.

The Daily News notes that in the minutes before the deadly shootout, Rosales had violated a restraining order and taken Giattino and their young son hostage in a nearby apartment after tracking them for a day.

Rosales had been arrested by Suffolk county police 17 times between 1998 and 2016, according to the Times, on charges that included felony assault. The paper reports he was jailed from 2006 to 2010, as well as 2012 to 2014. Speaking to the Times, Rosales's father alleged that his son had received second chances from the justice system because of his light-skinned complexion, pointing out that his "darker-skinned siblings" received harsher sentences for less smaller crimes.

"If anyone is truly to blame for this tragedy, I blame Suffolk County District Court and the judge who let him walk out of there knowing he was in mental distress, knowing he needed immediate psychiatric care," Giatino argued. "Because of this GROSS negligence, two husbands and two fathers are lost."

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.
