The man accused of sending a threatening email to faculty and staff at Roger Williams University Law School and engaging in an 8-hour standoff police appeared in court on Thursday.
Police say they found several guns, including rifles, a shotgun and a pair of handguns, and books about serial killing and making methamphetamine Kevin Pacheco's home.
His attorney said he meant no harm.
The judge agreed with the prosecution, saying that there should be a dangerousness hearing. Pacheco is being held without bail pending the hearing on Monday. There will be witnesses testifying against him.
Pacheco, 36, sent a 33-page email to faculty, threatening professors at Roger Williams University Law School.
"Today you will receive your last warning. Tomorrow I will draw blood against my enemy, stand by my side today or tomorrow I'll walk all over you," the email said.
Towards the end he allegedly wrote "Justice will be swift and it'll be without mercy."
Police engaged in an eight-hour standoff in Dartmouth, which ended after police cut the power. Pacheco surrendered peacefully.
Relatives stated that Pacheco had been hearing voices and had made various suicidal threats, although they said he wouldn't hurt anyone.
