Police: Guns, Ammo, Serial Killer Book Seized After Standoff With Former Roger Williams Law Student

DARTMOUTH (CBS) - Investigators have recovered guns, ammunition and books about becoming a serial killer and manufacturing methamphetamine from the home where a former law school student at Roger Williams University in Bristol, R.I. was involved in an eight-hour standoff on Tuesday, officials said.

Police say the standoff began after Kevin Pacheco, 36, sent a violent and threatening email to his former professors.

Pacheco was taken into custody Tuesday night. At the time, his family members had claimed he did not have any weapons, although he apparently told investigators he was armed.

Early Wednesday morning, police executed a search warrant at the Richard Street home, which belongs to Pacheco's father.

"As a result of the search, detectives recovered numerous firearms, ammunition, and computers, as well as books related to becoming a serial killer and manufacturing methamphetamine," a statement from Dartmouth Police said.

Police say Pacheco did have a firearms license at one point, but it is believed to be expired.

Pacheco faces charges of extortion and threats.

He is currently being evaluated at St. Luke's Hospital in New Bedford.
