University of Massachusetts Police searched a Baker Hall dorm room early Thursday morning, seizing multiple drugs, drug paraphernalia, cash, weapons and written records.

UMPD forces arrested Andrew D. Crossman, 20, of 2 Rice St. in Hudson, Mass., and charged him with possession of class B, C and D substances. Crossman was also charged with carrying a dangerous weapon, a knife with brass knuckles attached, possession of a hypodermic needle and possession of a class B substance with intent to distribute.

UMass police spokesman Jim Lyons said the search, which was carried out at 6:17 a.m., was conducted with a warrant based on the investigation of UMPD detectives.

“There were a bunch of different pills that would normally be prescription pills,” Lyons said.

Several other things were seized, including about $200 in cash and scales. Lyons said the police officers searching the room also found white powder residue that could potentially be cocaine, a straw and a mirror. It has not yet been determined if the residue is cocaine though, according to Lyons.

“All this stuff has been sent off to labs to confirm what it is,” Lyons said.

Several other drug busts have been made on campus this semester.

On March 3, police officers made a search of a room in Coolidge Tower. They seized several bags of marijuana, a digital scale and $378 in cash. Two arrests were made in the incident. Jacob Lasecki, 19, of Leominster, Mass., was arrested and charged with possession of a class D substance and possession of a class D substance with intent to distribute. Stephanie Lamrose, also of Leominster, was arrested and charged with possession of a class D substance.

On Jan. 31, UMPD officers responded after a call was made reporting a large party in Washington Tower. The responding officers obtained a search warrant for a room. They arrested Kevin M. Doherty, 19, of Revere, Mass., and charged him with possession of a Class D substance (marijuana) with intent to distribute, possession of a Class C substance (mushrooms) and possession of alcohol while under the age of 21.

The UMPD made the biggest drug bust in 30 years at the University on Nov. 12. Over $24,000 in cash, a large amount of marijuana and drug paraphernalia were seized when officers entered a room in Kennedy Tower while executing an unrelated search warrant for a stolen laptop computer traced by OIT to the room. The laptop was also recovered.

The two roommates were immediately arrested and charged. Steven Y. Nguyen, 20, of Southborough, Mass., was charged with receiving stolen property valued at more than $250 (the laptop), possession with intent to distribute a Class D substance (marijuana) and possession of a Class D substance. His roommate, Yuta Nakamura, 22, of Singapore was charged with possession of a Class D substance.

Another large drug bust involving UMass students was also made on Feb. 20 off-campus, with two related searches in Amherst apartments resulting in the seizure of four pounds of high-grade Canadian marijuana, $12,000 in cash, three safes and a BB gun from 394 Puffton Village and several different kinds of drugs from an apartment at 44 Mill Hollow Apartments on Summer Street. The seizure included hundreds of Adderal pills, a prescription amphetamine and medicine similar to Ritalin.

UMass student Jesse S. Schauffer, 22, was arrested in connection with the Puffton raid in his apartment and was charged with possession of a class D substance, marijuana, with intent to sell.

UMass student Leah B. Kimmel, 22, of Swampscott, Mass. was one of three people arrested in the Mill Hollow raid. Kimmel was charged with possession of a class B substance (oxycodone) and possession of a class D substance.
