A 17-year-old girl who grew up in Rindge and moved to Phoenix was fatally shot by a former boyfriend this week as she walked home from school, authorities said.

Kaitlyn Sudberry, remembered as sweet, caring and quiet by staff at Rindge Memorial School and Jaffrey-Rindge Middle School, was killed Monday by former boyfriend Daniel Byrd just a few blocks from her home, police said.

Byrd, also 17, then fatally shot himself, police said. Police pronounced the two dead on the scene after a neighbor found their bodies.

"It was really a shocker to hear the news," said John J. Stone, principal at Rindge Memorial School. "She was one who cared about everybody, such a sweetheart."

Born in Tucson, Ariz., Sudberry moved to the Monadnock Region in 1998 with her mother and younger brother after living for several years in Norwood, Mass., with her maternal grandparents, according to her grandmother Edith Hale, now of Marlborough, Mass.

Sudberry was a senior at Moon Valley High School in Phoenix, where she lived with her father, Richard Sudberry, and stepmother, Bobbi Sudberry.

She was planning to attend Northern Arizona University in the fall.

Lorie Forrest, Sudberry's aunt, told the Arizona Republic that Sudberry and Byrd broke off their one-year relationship about a month ago and Sudberry was ready to move on.

According to court documents, Byrd had threatened her life, assaulted and harassed her.

Sudberry's family had started paperwork for an injunction against harassment last week, according to the Republic.
