History:
(All-True Crime Cases Comics I#27/4) - In 1909 as a rookie police
officer, John Osnato was assigned to the lower east side waterfront,
one of the toughest beats in Manhattan. Osnato continued on this beat
until 1912 when he was involved in a shootout. Osnato's parents
expressed their concern about the danger he was being placed in and
asked him to give up being a police officer. John refused because he
wanted to become a detective. However, not long after, there was a gang
war on the lower east side. When John's mother heard about this, she
suffered a collapse. Concerned about his mother's ill health, John
agreed to give up being a police officer.
For 6 years, Osnato worked as a businessman to appease his parents but he grew listless and depressed. Recognizing how important police work was to him, his parents encouraged him to rejoin the force. John returned to the police in 1918 and was assigned to the Brooklyn waterfront. By 1919, John was promoted to become a plainclothes detective. John was assigned to work alongside policewoman Helen Burns to break up a bootlegging ring in Brooklyn. When John told Helen the work could be dangerous, she retorted "I adore shooting! Want to see the notches on my gun?" John and Helen worked together in Brooklyn and caught Toomey, the head of the bootlegging ring. After completing this case, John and Helen were married and John was promoted to detective, second grade.
John enlisted the small-time criminal Weasel Face as a stoolpigeon, noting that 50% of the big cases were broken with stoolpigeons. Sure enough, after one murder, Weasel Face informed Osnato that the killers were the hired triggermen Benny the Dope and Joey Fato. Osnato arrested them and soon obtained their confessions.
In September 1930, Osnato was assigned to investigate the kidnapping of Louis Gordo's son. Although Gordo had paid $10,000 to the kidnappers, they were still threatening him for more money. Osnato spoke to Gordo, who told him that all of his family's lives had been threatened. Osnato put a tap on Gordo's telephone and overheard a call in which the kidnappers demanded another $5,000. Osnato had the call traced and the kidnappers proved to be Gordo's own brother-in-law and his two cousins. The three men were arrested. On another occasion, Osnato investigated a Brooklyn cobbler-killer who refused to name his accomplice. Osnato played "good cop" with the killer, making him think Osnato's fellow officers would harm him and that only he could protect him; the killer gave up the name of his accomplice to Osnato as Bower.
As the years passed, Osnato received four departmental citations for his work on big cases such as the $427,000 Rubel Ice Corp. robbery. In 1940, Osnato was assigned to crack Murder, Inc., the organization of hired killers. Osnato decided to use Duke Maffetore as a resource to bring down Murder, Inc., as Maffetore was already in their custody and known to be connected to them. Osnato plied Duke by suggesting his allies had left him to rot in prison while they enjoyed the "gravy" of the proceeds. Finally, he started to get tough with Duke, suggesting he would deprive him of the luxuries he'd permitted in his cell. Duke finally revealed he'd been the driver for a number of killings and gave up the names of the leaders of Murder, Inc. Duke's confession enabled the arrest of Buchalter and a half-dozen other killers, bringing an end to Murder, Inc.
In 1944, John retired from the police force to a quiet suburban life with Helen. When she asked him to chop some wood for her, she found him chatting to their neighbor Joe about "the Adonis Club murder case" he'd once solved.
Comments: Adapted from the real-life John Osnato by an unidentified writer and Gene Colan.
Wikipedia has an article on the real-life Murder, Inc., who were indeed opposed by the real John Osnato. Osnato died in 1945, aged 55. Here's his New York Times obituary. It's a little strange that the comic story doesn't mention his death, given that it was published 3 years after his passing.
This story is believed to be only the 2nd published story drawn by Gene Colan.

Helen Burns was a red-headed policewoman. By the time she and John Osnato were assigned to work together in 1919 as plainclothes detectives, Helen had already been in several firefights and would notch the handle of her gun as a memorial. When John expressed concern about Helen accompanying him into a possible shootout, she retorted "I adore shooting! Want to see the notches on my gun?" They worked together to investigate Toomey, a bootlegger operating in Brooklyn. After arresting Toomey and his gang, Helen and John were married. They remained together in 1944 when John retired from the police force.

Louis Gordo was a baker whose son was kidnapped. The kidnappers demanded $10,000 which Gordo paid but they refused to release his son and threatened the lives of Gordo's family unless they paid out more money. Gordo informed the police of the situation and John Osnato was assigned to the case. Osnato put a tap on Gordo's phone and when the kidnappers called to demand another $5,000, Osnato traced the call. The perpetrators proved to be Gordo's brother-in-law and two of his cousins. All of the men were arrested.

Duke Maffetore was a criminal associated with the Murder, Inc. cohort of hired killers, serving as a driver for some of their killers. After Duke was arrested, John Osnato applied pressure on him to break up Murder, Inc., first weakening his loyalties to the mob by suggesting to Duke that while he rotted in prison, the leaders of the mob were enjoying the "gravy" of their proceeds. Finally, Osnato threatened to withdraw the luxuries Duke enjoyed. At this, Duke gave up the names of all the leaders he knew. His testimony brought an end to Murder, Inc. and led to the arrests of several members of the mob.

The real-life man was named Anthony "Duke" Maffetore.

John Osnato's parents were very concerned about the violence in his job, especially during his early years when he served in the lower east side waterfront. In 1912, they asked John to give up his career as a policeman but he refused. Not long after that confrontation, John's mother heard about a gang war in the lower east side. Concern for John caused her to suffer a collapse. Concerned for her health, John agreed to give up being a policeman and went into business. By 1918, John's parents could see he was depressed and gave him their blessing to resume being a police officer, aware that it was what he truly wanted.
