NORTHAMPTON — A Holyoke man accused of assault to murder and several other charges was ordered held without the right to bail at his arraignment Monday in Hampshire Superior Court pending a dangerousness hearing.

Through his attorney, Robert Opsitnick, Hector Diaz Torres, 22, pleaded not guilty to five assault charges stemming from an alleged knife attack on Jan. 13, as well as four charges from an incident Dec. 6 related to alleged cocaine trafficking and distribution of fentanyl. Both cases were moved up from Northampton District Court following Diaz Torres’  indictment by a grand jury on Feb. 15.

Judge Edward McDonough set bail at $10,000 on the drug charges at the request of Opsitnick and Assistant District Attorney Joe Webber. A dangerousness hearing for Diaz Torres was set for March 29.

According to Webber’s filing in support of his motion for detention, Diaz Torres attacked a man who had come to his girlfriend’s residence to buy drugs. When the man showed up between 9 and 9:30 p.m., Diaz Torres answered the door, told him to come inside and ordered him downstairs, where he began beating him with a metal pipe, according to the court filing. After a brief respite, Diaz Torres emerged from an adjoining room, charged at the man, “screaming that he was going to kill him, and then stabbed him in the chest with a knife,” the filing states.

The man was taken to hospital where staff told him the knife wound was close to being fatal.

Diaz Torres has a lengthy criminal record of violence and weapons-related charges, Webber stated. At the time of the alleged knife attack, he was on pretrial release for the felony drug charges out of District Court and on probation in Hampden County on assault and weapons charges.

The charge of assault to murder carries a maximum sentence of 20 years in prison.

Diaz Torres’ girlfriend, Katherine Feliciano, and a third defendant, Evelyn Munoz, also were arraigned Monday in Superior Court on charges of cocaine trafficking and distribution of a class A drug. Both were released on $2,000 bail previously posted in Northampton District Court.
