Police officers worked Sunday at the scene of a fatal shooting Saturday night on Old Granite Street, a side street just off Elm and Granite streets in Manchester.

MANCHESTER — Police are investigating the death of 34-year-old Tanya Hall, who died of an apparent gunshot wound, authorities said.

Attorney General Gordon J. MacDonald and Manchester Police Chief Carlo T. Capano announced in a joint news release Sunday that the woman’s death is “suspicious” and more details would be released once an autopsy has been performed.

“It’s an open investigation. That’s really all I can say at this point,” Assistant Attorney General Peter Hinckley said.

Hinckley said the crime scene was on Old Granite Street, a side street just off Elm and Granite streets that is home to two popular nightclubs.

Authorities asked that anyone “in the Manchvegas Bar and Grill, or in the area of Old Granite, Granite, and Elm streets” on Saturday night or early Sunday with information about the incident contact the Manchester Police Department Detective Unit at 603-668-8711.

Hinckley declined to comment on whether the Old Granite Street crime scene was related to another a few blocks away, where an ambulance was called for a shooting victim around 11:45 p.m. Saturday. That area, near Pine and Auburn streets, was also blocked off for several hours as police processed the scene. A blue Jeep was towed away, followed by police cruisers.

Manchester police referred all calls to the Attorney General’s office.

Hinckley said an autopsy is to be performed Monday at the State Medical Examiner’s office in Concord.

Club Manchvegas, at 50 Old Granite St., posted a statement on Facebook on Sunday apologizing to customers affected by the incident and clarifying that it happened outside.

“Unfortunately due to an incident in the parking lot across the street, the Manchester Police Department made the incident an active crime scene. We understand it was frustrating and a hassle to get out of the club last night, but unfortunately it was out of our hands,” the statement said.

Jack Thompson, owner of Club Manchvegas at 50 Old Granite St., said Sunday that he was inside working when police started arriving at the scene. Thompson said whatever led to the incident happened outside in a parking lot and that nobody from the club was involved.

A message left at Whiskey’s 20, just uphill from Club Manchvegas at 20 Old Granite St., was not immediately returned.

Thompson said police focused Sunday on the parking area sandwiched between Old Granite and Granite streets and west toward Canal Street, where a Jeep matching the description of the one towed away from Pine and Auburn streets was seen leaving the lot toward Canal Street.
