A San Diego woman is playing a key role in what police are calling the worst killing in 20 years.
Barb Weith, 64, is the widow of San Diego businessman Peter Weith. He was killed, along with two of his business partners, near Las Cruces, New Mexico in April. Police in New Mexico are interested in talking to Weith, but so far she is refusing to cooperate.
So far, there have been no arrests for the murders of Peter Weith, 68, Gilles Delisle, 69, and Helga Delisle, 72, but police say they have some leads.
"We do have very good evidence linking some persons of interest, which I cannot divulge, to this crime," said Dona Ana Sheriff's Sgt. Joe Reynaud.
Reynaud told the Las Cruces Sun-News that Weith needs to corroborate information authorities were provided in a recent tip.
However, Reynaud says Barb Weith fears for her life. Earlier this year, Weith told police she received two threatening phone calls at her San Diego home, which detectives tracked down to a pay phone on the Canadian border.
Reynaud says the phone calls scared her into hiding, because Weith believes they may have come from her husband's killer.
"She has taken steps to protect herself, meaning she is no longer living at her residence in San Diego," Reynaud said.
Barb Weith has refused to be interviewed since the three victims were shot in the Delisles' home in Mesilla, NM, eight months ago. Weith claims she is afraid to travel to Las Cruces. Reynaud says he is working to set-up an out-of-state interview.
"We do have her phone number; we have talked to her on the phone; we do not know where she is at," said Reynaud.
Earlier reports said Barb Weith was a "person of interest" in the case, Reynaud says that is simply not true.
There is a $10,000 reward for any information leading to an arrest in the case.
