(WIVB) – Charges against a Depew man accused of killing his wife have been upgraded to first-degree murder.

Sayed Nasir, 38, is accused of breaking into his ex-wife’s home and stabbing her to death.

The woman, 33-year-old Nazeefa Tahir, died at the scene.

Prosecutors say the charges have been upgraded because Nasir violated an order of protection when committing the crime.

“Now that it’s murder in the first degree he is not eligible for parole, basically, and he could go to jail for the rest of his life,” said Erie County District Attorney John Flynn.

If convicted, he faces life in prison.
