Friends and family of a Franklin girl shot and killed in Boston Sunday night said they are shocked and saddened by her death.

Natalie Sumner, 18, was killed in an apartment in the city's Allston neighborhood at about 9:30 p.m. Sunday. Julio Ceus, 33, a resident of the apartment, was also shot and killed.

A friend of Sumner's, Ashley Bjelf, 18, of Laconia and Belmont, N.H., was wounded in the shooting.

According to the Boston Herald, the shooting might have been drug-related. Ceus' brother, Bermane Ceus, said that Bjelf explained to him what happened.

"He was in his apartment upstairs, and two black guys went up in there and they shot Natalie and Julio," Bermane Ceus said.

That differs from the police report, which said one of the gunmen was white.

Bjelf's stepmother told the New Hampshire Union Leader that a bullet grazed her neck. Bjelf was treated and released at Beth Israel Hospital.

On Tuesday morning, Sumner's mother, Melissa Foley, said she was having trouble dealing with the murder. Foley said she wanted some answers about how and why Sumner was killed.

At Franklin High School, where Sumner was a junior, grief counselors were on hand. Sumner played on the girls basketball and field hockey teams.

"She had presence. She always had this bright, shinning face," said Karleen Pelletier, Sumner's teacher. "She had so much going for her, and I'd like people to remember her that way."

Foley said that her daughter was having trouble in school, and poor grades forced her to drop out of sports, but she never thought that Sumner might be into drugs. Foley said that she thought Sumner was going to Allston to visit some friends, like she often did.

Police have reported that one of the victims was shot in the head and the other in the back, but Foley said she's upset that police won't tell her exactly how her daughter died.
