Police are now linking two separate shootings of Brooklyn store owners in the last month.
Ballistics evidence from the two incidents match up, meaning the same weapon was used, though not necessarily by the same person.
This comes as the NYPD released a sketch of the man they want to speak with in connection with Thursday night's shooting in Bensonhurst.
Authorities describe him as being in his 20s, 5-feet-9-inches tall with a medium build.
Two customers found the body of Isaac Kadare, 59, inside his 99-cent store on 86th Street and 19th Avenue.
The medical examiner ruled it a homicide after finding a gunshot wound to the head and sharp wounds to the neck.
Sources say Kadare's face was covered with an aluminum tray and his pants were splashed with bleach.
They are offering $10,000 for information in Kadare's case.
This also comes as police raised the reward to help find the person responsible for killing Mohamed Gebeli, 65, on July 6.
Gebeli was shot and killed inside Valentino Fashion on 5th Avenue in Bay Ridge.
Police are now offering $12,000 for information in the case.
State Senator Martin Golden, who is contributing reward money to help solves these crimes, said there are similarities in both cases that point to one shooter.
Both victims were originally from Egypt, they were shot and killed in their stores at the end of the work day, and perhaps most unusually, Golden said the victims' faces and part of their bodies were covered after they were killed.
"There are certain things that went on in these murders that you don't normally see," said Golden.
A day after Kadare was buried, his family and friends sat shiva on Saturday. They, along with the Gebeli family, told NY1 they hoped this latest development meant police were closing in on the criminal who upended their lives.
"The American dream they came to reach in this country became an American nightmare. It's sad. That's why we have to resolve this, these families are broken," said Golden.
