ROCHESTER, N.Y. -- An arrest has been made in connection with a Rochester homicide investigation last month.

Amari Brown is expected to be arraigned in Rochester City Court on Friday on a second-degree murder charge.

Investigators say the 22-year-old Rochester man stabbed 42-year-old Monica Sherman of Rochester at a home on Lyell Avenue on July 24. She died at the scene.

Officers responded to a call shortly before midnight to a call of a body found, and launched the investigation. 

There's no word on a possible motive.
