CHESAPEAKE — Six members of a Chesapeake family that friends and neighbors called religious and hard-working were killed in what apparently was a murder-suicide after a failed negotiation, police said Thursday.

Chesapeake police said they believe Cameron Dooley, 26, killed his parents, brother, sister and another relative before killing himself after an hours-long negotiation with officers.

The other dead were identified as Steven Todd Dooley, 50; Lori Dooley, 54; Landon Dooley, 22; and Brooke Dooley, 17. The name of the sixth family member, a woman, was not immediately released.

Steven Todd Dooley, who went by his middle name, retired Nov. 1 after 25 years as a Chesapeake police officer, spokeswoman Kelly O’Sullivan said. Several neighbors said Todd Dooley’s father, the Rev. Allen Dooley, led the nearby Temple Baptist Church before dying in 2010 and leaving behind a large family that was widely viewed as the cornerstone of the neighborhood.

“They were just really good Christian people,” neighbor Desiree Darst said by telephone. “I knew them my whole life. We’re all in shock.”
