MANCHESTER, N.H. -- A mother of six is dead and another person is hospitalized with serious injuries after a man entered the apartment early Saturday morning, investigators said.

At about 4 a.m., Manchester police responded to a call at 168 Valley St., where officers found the body of Edith Riley, 35.

"We love my mom so much," Riley's son, Matt, said. "It seems like a bad dream."

"I still can't believe she's gone. I'm not really realizing it in my head," said Jennifer Tardiff, who lives in an apartment upstairs.

Timothy King, 21, Riley's live-in boyfriend, was seriously injured in the incident. He remained hospitalized at Massachusetts General Hospital by the late afternoon.

Authorities arrested Todd Peters, 35, of Weare, and charged him with second-degree murder. There was no official word on whether Peters knew the victims, whether a weapon was found or what transpired. An autopsy for Riley is scheduled for Tuesday morning.

Investigators said they do not believe the public is in danger, and they would not say whether officials anticipate making more arrests.

WMUR News 9's Aaron Kellogg reported that police streamed in and out of the house throughout the day Saturday.

Riley's relatives said someone entered her apartment, where four children were inside at the time. Relatives also said Riley's 12-year-old daughter watched and called 911. Associate Attorney General Ann Rice gave no details on what prompted the call.

"My mom was screaming for my sister, and my sister, she ran out and tried to do what she could," Matt Riley said.

Some neighbors said the homicide stemmed from a neighborhood dispute.

"I specifically said yesterday, 'Is it going to take someone to die to get this solved?' And, obviously, it did because my house is now a crime scene," Tardiff said.

The state attorney general's office and Manchester police continue to gather information and interview people in this continuing investigation.

"We all love you so and we miss you so much. It's really hard mom," Matt Riley said. "I love you so much."
