Police are questioning a boy who accidentally shot his sister about the whereabouts of the person he received the gun from. The gun was used in another shooting earlier this week.

A 12-year-old Queens boy who accidently shot his 14-year-old sister in the stomach Friday used the same weapon that killed Mohamed Hamwi, 48-year-old systems analyst who was shot in the in the face and chest Tuesday, according to The New York Daily News.

Police believe Hamwi’s death was a robbery gone wrong as he still had iPhone and $200 on him when his body was found.

According to The New York Post, the 12-year-old boy was playing with the gun around 2:25 am when a family friend told him to stop playing with the gun.

He ignored her, told her not to worry about what he was doing, and continued pulling the trigger until it went off and a bullet pierced his teenage sister’s abdomen.

She was rushed to Jamaica Hospital and is recuperating.

Police have questioned where the boy got the gun, but he is telling conflicting stories. He once stated he found the gun on the street, then said a friend gave it to him.

“We don’t know where he got the gun. He wouldn’t tell us. He is not saying nothing to nobody,” the boy’s sister told The New York Daily News.

Mohamed Hamwi’s body was found just ten blocks from the boy’s apartment and police are still investigating his death.

Hamwi leaves behind a husband and a mother-in-law, neither of whom believe hate was a motivator for the crime, according to The New York Daily News.

“You couldn’t ask for a nicer person,” Hamwi’s mother-in-law, Zona Tomlinson, 59, said.

Hamwi’s body was identified by his mother-in-law. His husband was too distraught to identify him.

“He didn't want to see him like that,” Tomlinson said of her son. “He was afraid of how he'd look.

Hamwi was from Syria and raised Muslim, however, he did not practice the faith because of its prohibition against homosexuality.

The boy who shot his sister is apparently known in the system. He has been cited for trespassing and authorities have been called to his home for incidents he causes.
