SolvedFingerprint

Concetta 'Penney' Serra

New Haven, Connecticut · 1973

Concetta 'Penney' Serra, a 21-year-old dental assistant, was chased through the Temple Street parking garage in downtown New Haven, Connecticut, and stabbed once in the chest on July 16, 1973. The case became one of Connecticut's most notorious unsolved murders, including the wrongful 1984 arrest of an innocent man, before forensic advances finally identified the killer. A bloody fingerprint left on a tissue box in the victim's car was matched in 1997 to Edward R. Grant, a Waterbury auto-body worker, and DNA from a bloodstained handkerchief at the scene confirmed the link. Grant was arrested in 1999 and convicted of murder on May 28, 2002, nearly 29 years after the crime.

SolvedWitness / tip

Jumar Joiner

Hartford, Connecticut · 2008

Jumar Joiner, a 25-year-old man from Windsor, Connecticut, was fatally shot on May 3, 2008, in the area of West Morningside Street in Hartford. According to the Office of the Chief Medical Examiner, he suffered multiple gunshot wounds. In the days, weeks, and months after the killing, investigators followed up on tips and leads but made no arrest, and the case went cold for nearly a decade. In 2017, the Connecticut Division of Criminal Justice's Cold Case Unit received new leads through its tip line, including the names of two men who told police they had witnessed the shooting. That witness information helped lead to the March 2022 arrest of Mark White, who was then in custody in New Mexico on unrelated illegal-handgun and cocaine charges. A Hartford Superior Court jury found White guilty of murder on March 7, 2025, and on June 6, 2025, he was sentenced to 40 years in prison with credit for about six months already served.

SolvedBallistics

San Chiu Wong

New Britain, Connecticut · 1997

San Chiu Wong, the owner of a Chinese restaurant in New Britain, Connecticut, was shot in the back of the head and robbed in his own kitchen on March 17, 1997. The killing went unsolved for years. The break came not from a witness or a confession but from a gun: thirteen days after the New Britain robbery, Gino Gentile fired the same .380 caliber handgun in a shooting in Paterson, New Jersey, that left one man dead and two others shot. When firearms experts at the Connecticut State Police Forensic Laboratory compared the ballistics, they proved conclusively that the same weapon had been used in both states, tying Gentile, by then serving a 40-year sentence for the New Jersey killings, to the cold New Britain case. Gentile was convicted of felony murder, first-degree robbery and conspiracy and sentenced to 100 years, and his getaway driver, Edgar DeJesus, pleaded guilty to second-degree manslaughter and was sentenced to 19 years.
