Smith told investigators that she placed the gun under her friend’s bed in Lowell.

Smith is accused of possessing the murder weapon and misleading the grand jury, in addition to other charges.

Campbell and Jiggetts appeared in court on Friday as prosecution witnesses against Smith. During their testimonies, both acknowledged that Jiggetts and Copney had stolen marijuana from the Yale students, according to The Boston Globe,

According to Copney’s lawyer John A. Amabile, Copney has been charged as an accessory to the robbery of the Yale students.

Amabile said that he does not think that the robbery is pertinent to the Kirkland shooting case and has asked that the judge dismiss the charge.

“Why is that relevant to whether [Copney] committed a murder six months later in the basement of a Harvard dorm?” Amabile said. “It will make the jury think [Copney] is a bad person.”

Salem Superior Court Judge John Lu—who Amabile said will preside over Copney’s upcoming trial—will review Amabile’s motions to dismiss the charges relating to the New York robbery or separate those charges into a different trial in Salem on Monday.

Both Bolton and King did not respond to phone calls yesterday afternoon.
