As Virginia Beach mourns 12 people gunned down in a shooting rampage, more questions remain on why a veteran city engineer targeted people he'd worked with for years.The gunman fired indiscriminately Friday on a municipal building in the coastal city in Virginia before he died after a long shootout with police officers.As officials struggle for answers, Mayor Bobby Dyer has tried to quell both sides of the gun control debate, saying he wanted to avoid the "knee jerk reaction" and the "bipartisan bureaucratic malpractice.""There's a lack of civility. There's a lack of mutual respect. There's a lack of willingness to understand each other," Dyer said Saturday.Here is what we know so far -- and what we don't.The mass shooting and the targetWhat we know: The shooter was a "disgruntled employee" in the municipal building he attacked, a Virginia government source said.On Friday toward the end of the work day, he shot one person in a car and then entered the building where he fired at people on three floors.What we don't: Authorities are still searching for a motive, and those who knew him say they didn't see the horror coming."I guess the big question is, why? We want to know, too," Dyer said.Joseph Scott said he worked with the shooter for several years and saw him that day. He said the suspect was brushing his teeth in the bathroom, as he always did, and wished him a good day. He was "what I thought was a good person," Scott said of the shooter.The victims and their conditionsWhat we know: Twelve people were killed in the attack and several others were wounded, with three people in critical condition and one in fair, hospital officials said Saturday.Those killed include Herbert "Bert" Snelling, who was trying to file a permit when the gunman opened fire.Three right-of-way agents were killed: Laquita C. Brown, with four and a half years years in the public works department; Mary Louise Gayle, with 24 years in the department; and Alexander Mikhail Gusev, with nine years in the department.Also slain were engineers Tara Welch Gallagher, who spent six years in the city's public works department; Katherine A. Nixon, who worked in public utilities for 10 years; Richard H. Nettleton, who worked for the city's public utilities department for 28 years; and Christopher Kelly Rapp, who had been in public works for 11 months.Joshua O. Hardy, an engineering technician for four and a half years in the public utilities department was also killed, as was Ryan Keith Cox, an account clerk, who had spent 12? years in the public utilities department.Also killed in the attack were Michelle "Missy" Langer, an administrative assistant who worked 12 years in public utilities, and Robert "Bobby" Williams, a 41-year veteran in the public utilities department and special projects coordinator.What we don't know: Why their workplace was targeted.The investigationWhat we know: 40 members of law enforcement, mostly FBI, were at Building 2 to collect evidence.They found two legally purchased .45-caliber pistols at the scene -- one the shooter bought in 2016 and one in 2018.Police said one pistol had a suppressor and several empty extended magazines. And Investigators found even more weapons in the gunman's home, Chief James Cervera said.What we don't: Questions remain about why he purchased the weapons and how long he was planning his attack.The gunman and his family What we know: The gunman was identified as 40-year-old DeWayne Craddock, who worked as a certified professional engineer in the city's public utilities department for 15 years.His neighbor, Clarisa Morel, said the gunman had three security cameras set up in two of his windows and once catcalled her.Another neighbor, Cassetty Howerin, said he was awake all hours of the night, but mostly kept to himself.What we don't: We don't know if the gunman had previously threatened anyone in the building or had conduct issues at work; Cervera declined to answer questions about that Saturday.The shooter's parents, reached Friday night, told CNN they weren't aware of any trouble that he was having with his employer. The family posted a handwritten message on their front door but focused on the victims rather than the perpetrator."We are grieving the loss of our loved one. At this time we wish to focus on the victims and the lives (lost) during yesterday's tragic event," they wrote. "Our thoughts and prayers are with the families of those who (lost) their lives, and those recovering in the hospital. -- The Craddocks." 4526

B. Don Russell wasn’t thinking about preventing a wildfire when he developed a tool to detect power line problems before blackouts and bigger disasters.The electrical engineering professor at Texas A&M University figured he might save a life if his creation could prevent someone from being electrocuted by a downed live wire.But fire prevention may be his product’s biggest selling point in California and other places that have experienced devastating wildland blazes blamed on electrical equipment.“If we can find things when they start to fail, if we can find things that are in the process of degrading before a catastrophic event occurs, such as a downed line that might electrocute someone or a fire starting or even an outage for their customers, that’s kind of the Holy Grail,” Russell said.The technology he bills as a one-of-a kind diagnostic tool called Distribution Fault Anticipation is now in use in Texas and being tested in California by Pacific Gas & Electric Co. and Southern California Edison. The utilities have been blamed for some of the most destructive and deadliest fires in California.Texas A&M said the technology will also be tested in New Zealand and Australia, which is currently reeling from destructive wildfires.The tool detects variations in electrical currents caused by deteriorating conditions or equipment and notifies utility operators so they can send a crew to fix the problems, Russell said.It can anticipate many problems in their early stages — sometimes years before they cause an outage or present a greater hazard during high winds when utilities are now pre-emptively shutting off power to prevent sparking wildfires.Before the technology was developed, electric companies often didn’t know they had a problem until there was a failure or a customer called to report sparks on power lines or a loss of electricity.“The assumption the utility has to make today is it’s healthy until we get a call that says somebody’s lights (are) out,” Russell said. “By then the fire’s started or the outage has happened or the person’s electrocuted.”Pedernales Electric Cooperative Inc. that serves about 330,000 customers outside San Antonio and Austin, Texas, began implementing the system after successful tests that began in 2015. The utility serves areas so rural that before the technology was installed, electricity powering a pump on a well could have been off for days before being detected by a farmer.The devices installed at substations are now trouble-shooting all kinds of problems, said Robert Peterson, principal engineer for the utility.“We’ve found tree branches on the line. Failing arrestors. Failing capacitors. Failing connections,” Peterson said. “It’s pretty amazing.”In California, the testing process has just begun and there are no results yet, according to PG&E and SoCal Edison.In Southern California, the software is running on just 60 of Edison’s 1,100 circuits in the utility’s high-risk fire zone, which accounts for about a quarter of its total circuits.It’s just one of several tools the utility is testing to continue to modernize its system.“There is no silver bullet,” said Bill Chiu, managing director of grid modernization and resiliency at SoCal Edison. “This is really more of a preventive measure. ... The important point is this will be one of the suite of technology that will help us better assess the condition of the grid.”Chiu said the technology was not at the point where it could be used to determine where to shut off power when dangerous winds are forecast during dry conditions. He also said it won’t pinpoint problems but can help dispatch crews closer to the source of equipment that needs to be fixed, saving time that would be wasted patrolling miles of power lines.One question is whether the technology is economically feasible to deploy across tens of thousands of miles of power lines, Chiu said.At an expense estimated between ,000 to ,000 per circuit, it could cost the utility million in its high-risk fire area and that doesn’t include installation, operation and maintenance costs.That’s a fraction of what a moderate wildfire sparked by a utility could cost, Russell said.PG&E, which is testing the technology on nine circuits, was driven into bankruptcy protection this year while facing at least billion in losses from a series of deadly and destructive wildfires in 2017 and 2018.SoCal Edison recently agreed to pay 0 million to local governments to settle lawsuits over deadly wildfires sparked by its equipment during the last two years. That figure doesn’t include lawsuits by thousands who lost their homes in those fires or family members of 21 people killed when a mudslide tore down a fire-scarred mountain. Two other people were never found.Bluebonnet Electric Cooperative found the cost was feasible and has installed it on about a sixth of its circuits for the utility that has about 100,000 customers in Central Texas, said Eric Kocian, chief engineer and system operations officer.While the system has helped proactively diagnose problems and detect the cause of outages, the university team that developed it can often find problems the utility’s control room operators don’t detect.Pedernales Coop is working with an analytics company to streamline the analysis of the myriad information the software evaluates to find and fix problems in a day, Peterson said.Russell said he never had a hint the device his research team created 15 years ago would have fire prevention applications until a series of bad wildfires in Texas in 2011. They were focused on keeping power systems safe and the lights on.“It’s obvious now in today’s context of the drought that we’ve had in California and other places,” Russell said. “Serendipitously, that’s where we find ourselves today.” 5838
