, as the Venezuelan company is also known, Costa said. Petrobras will build the 230,00-barrel-a-day facility solo with its own financial resources should PdVSA back out of the deal, the executive added. Petrobras included the full cost of construction of the $16 billion, 230,000-barrel-a-day refinery in its business plan just in case, Costa said. "There won't be any problems, no delays," Costa said. "I had to have two alternatives in hand," Costa said, noting plans for the refinery with or without PdVSA as partners. "Now, what's important in the hypothesis that [PdVSA] doesn't participate is that the work is going to continue normally without any financial problems." PdVSA needs to reach a deal with the BNDES on its 40% share of the loan and ante up the additional cash needed to continue work on the refinery by August or September, Costa said. "Or, as we understand it, [PdVSA] will have lost [interest] or no longer has interest in participating [in the project]," Costa said. PdVSA is still working closely with the BNDES to hammer out the necessary loan guarantees, but Costa said that he has no information that a deal has been worked out yet. The refinery joint venture, however, has been fraught with difficulties from the start. In 2009, PdVSA and Petrobras finally reached a shareholders agreement after years of rancorous talks. Petrobras will have 60% of the project, with PdVSA holding 40%. The refinery has also been saddled with cost overruns, allegations of overcharges and difficult negotiations between Petrobras and PdVSA on crude oil supplies. Tlton that included a house, a guest house and hay fields. The two also made allegations of domestic violence against each other, and each obtained an order of protection against the other. In one filing, Dyess claimed Sigurdson kicked in his door and brought Clatone and other friends to his home to harass him. In 2007, Dyess filed a request for a protective order against Finney, whom he identified as Sigurdson's boyfriend. Dyess said the two had trespassed on his property, and he claimed Finney slowly drove by his house every day to intimidate him. A judicial officer rejected the request. Dyess was listed in court records as a retiree who had a pension, collected Social Security and made extra money by training horses. His friends saw no indication that he was planning an attack, Wilmot said. Dyess lived in Kitsap, Wash., during the 1990s, and family members from an earlier marriage live in the area, the Kitsap Sun newspaper reported on its website Saturday. Dyess' eldest son David Dyess of Port Orchard, Wash., told the paper Friday that he and his family were shocked by the shootings. "The entire family is upset about this, about the loss of him and his victims and victims' families." said David Dyess, who was described as estranged from his father. The paper reported that David Dyess, his mother and siblings are trying to reconcile the man they knew and lost track of with the horrific news. "I don't know who he is," David Dyess said. "I want answers, too." Authorities have found no notes left by Dyess, and haven't determined the order in which the killings occurred. They only know when the deaths were reported, Wilmot said. Officers received the first call around 5 a.m. about Clatone, who was shot at a home in Wellton, about 25 miles east of Yuma, Sheriff Ralph Ogden said. The bodies of Sigurdson, Finney, Simpson and the unnamed victim were then found in other homes around Wellton between 8:20 and 9:45 a.m. Dyess drove to Yuma and killed Shelley at his downtown law office at about 9:20 a.m., Ogden said. He then drove back toward Wellton, pulled over and shot himself. His body was found inside a vehicle at 10:47 a.m. Court records show Sigurdson and Dyess were married in Tombstone in May 2002 and filed for divorce in 2006. Their divorce was approved in 2007. It was Dyess' fifth, with the previous four divorces all in Washington state. During the proceedings, Sigurdson alleged Dyess abused her, and she asked for and received an order of protection. The file contained no details of the incident. Dyess also received an order of protection against Sigurdson, which barred her from going near his home. The order was later modified to give Sigurdson access to parts of the property. The two eventually agreed on a property split that gave Sigurdson the couple's home in Wellton once she bought out her former husband's share. A lawyer for Dyess filed
