The killer of longtime attorney Oliver "Chip" Northup and his wife, Claudia Maupin, in their Davis condominium remains unknown a month after police discovered their bodies April 14.
"This is priority No. 1. This attacks at the very essence of what we think is secure: the home," Davis Police Lt. Paul Doroshov said. "We would really like to find out who did this and why."
The grim scene at the couple's south Davis home in April stunned the city.
Northup, 87, an attorney and popular local musician, and his wife, Maupin, 76, beloved by friends and devoted to her church and community, were found stabbed to death.
For weeks now, investigators have been working to solve the killings. But police say they have few leads.
Dozens of detectives and others from the FBI and law enforcement from across Yolo County joined Davis investigators in the days after the killings.
Davis has seven of its detectives on the case and has been working closely with the Yolo County District Attorney's Office, Doroshov said. The FBI is still providing agents and other expertise, he added.
Police opened a telephone tip line, (530) 747-5439, almost immediately after the slayings hoping to shake loose more clues, but so far it has had little success.
Police want neighbors to recall those days in April and review home security images for anything that could be a clue for investigators.
"Think back on that weekend. Maybe there was something out of the ordinary," Doroshov said. "Some have set up videography. Maybe they want to look at the videotape they have - really, any kind of information they can arm us with."
In the Cowell Boulevard neighborhood of duplexes and condominiums that Northup and Maupin called home, neighbors continue their struggle to comprehend the tragedy.
"It is disturbing. It's disconcerting. It makes you feel different about the place," said neighbor Jim Stranahan on Monday.
Stranahan recalled a mourner bringing flowers to the couple's door, but he had no idea of their violent end until days after their deaths.
"You can't fathom it," he said. "You sure hope they figure out something."
