New York State Police investigators are helping Binghamton detectives as they work to determine who shot 12-year-old Aliza Spencer near her East Side home.

Mayor Jared Kraham Thursday morning thanked the state police "for their assistance in the ongoing investigation."

Binghamton police have released no information about the killing of the sixth grade student since last Friday.

According to state police, the agency's Forensic Identification Unit is assisting the Binghamton Police Department in its investigation.

Investigators have said Aliza was shot in the chest shortly after 10 p.m. April 21 in the area of Bigelow and Chamberlain streets as she walked with her father and brother.

Police rushed to the neighborhood to investigate "a report of shots fired." Although Aliza sustained a single wound, detectives have not said how many shots were actually fired in the incident. The girl was pronounced dead shortly after she arrived at a hospital.

In a tweet, Mayor Kraham said the reward for information leading to an arrest in the case is now $25,000 as a result of "additional matching funds" from people in the community.

Kraham last Friday afternoon announced the city was offering a $10,000 reward in an effort to generate useful tips in leading to the person responsible for the shooting.
