AMHERST — An arrest warrant has been issued for a man police believe is responsible for the deadly shooting that occurred at Southpoint Townhouses & Apartments late Friday night, according to a statement from Northwestern District Attorney’s Office spokeswoman Mary Carey.

Jose M. “Joselito” Rodriguez, 31, was killed in the shooting. A 28-year-old man was also shot that night.

Amherst Police is working alongside Massachusetts State Police assigned to the Northwestern District Attorney’s office. Police obtained the arrest warrant Tuesday afternoon from Eastern Hampshire District Court in Belchertown, according to the statement.

Local and state authorities are actively seeking the suspect, who they believe is no longer in the Amherst area, the statement said. Police declined to release the suspect’s name until he is in custody because the investigation is ongoing.

In the statement, Northwestern District Attorney David Sullivan called the arrest warrant a “significant and positive development,” and said the investigation is “active and ongoing.”

The 28-year-old victim underwent surgery at UMass Memorial Medical Center in Worcester. According to Carey, he will be released from the hospital “in the near future.”
