March 27, 1985: Vincent Charles Zazzara and Maxine Levenia Zazzara were both shot. On the same day, Tsai-Lian “Veronica” Yu was pulled out of her car and fatally shot twice. 22-year-old Maria Hernandez was shot at but survived. March 17, 1985: Dayle Yoshie Okazaki, 34, was shot in the forehead. Her throat was cut so deeply she was nearly decapitated. June 28, 1984: 79-year-old Jennie Vincow was stabbed repeatedly while asleep in bed. In June of that year, his Night Stalker killing spree began. He hung her body from a pipe in April 1984. His first murder was Mei Leung, a nine-year-old who he beat and raped before stabbing her to death. We will probably never know the actual number of murders he committed or the lives he ruined. The list does not include the women he raped before his murder spree, nor does it include a list of the children he molested. But if you look closer, near the death row cells, a smokestack left over from the gas chamber era is a visible reminder that the picture perfect location belies its purpose, which is to confine, and occasionally execute, California’s worst criminals. The prison sits on a pristine piece of land, worth hundreds of millions of dollars, on the San Francisco Bay. Richard said nothing as they approached San Quentin. Even though the media got wind of it the week after the sentencing hearing, they buried the story in the back pages. Disappointed, Richard asked, “Where is everyone?” It was quiet, just as it had been behind the jail in Los Angeles In order to keep security tight, they had not informed the media of the plan to move Richard. A Marin County deputy, standing next to an empty van, was the only person waiting for them. The trip to the small airport north of Novato was uneventful. Bud looked down and said to Richard: “You should go skydiving.” Richard replied he didn’t have a parachute. They flew out to the Sheriff’s Aero Bureau in Long Beach, where they climbed aboard a Cessna 210.Īs they flew north over Hollister, Bud, and Richard talked about the 6.9 earthquake which had occurred the previous month. Occupying the front seats were the pilot, and Sergeant Cecil Sabatine. He had undoubtedly planned a farewell performance.īud and Richard got into the rear two seats of a waiting helicopter which had landed behind the jail. The absence of press and groupies must have disappointed him. Richard wondered aloud where the crowds were. Bud fastened the waist chains and handcuffs. On November 16, 1989, Bud woke Richard up in his cell and told him it was time to leave. A narcissist, he thrived on the agony of others.ĭeputy Bud Phillips worked statewide transportation, and they had assigned him to deliver Richard to California’s Death Row at San Quentin in Marin County. This is most likely the basis of Ramirez's killings.Although he believed he was a mystery too intricate for ordinary people to fathom, he was not as complex as he thought. It was widely believed that Ramirez had encountered a satanic cult which told him that he must sacrifice human lives for Satan. For everyday after school the young Ramirez would go to the library to teach himself about the fallen angels and Satan. Ramirez, the youngest of seven children, did learn the Bible, but only in reverse. What drove Ramirez to start killing? Considering that when he was a young, his mother sent him to Sunday School to learn the Bible. While in California, he was arrested yet again for grand theft auto, but somehow he wasn't charged with the crime. When Ramirez was 20 years old, he left El Paso. He was placed on three years probation for this crime. His third arrest was for reckless driving. He was arrested a second time for the same crime. His first arrest as an adult was for possession of marijuana. He was known through his teenage years as a petty thief. Richard Ramirez was born in El Paso, Texas on February 28, 1960.

He has been critical of the opposing slate, arguing that they are “coming in with a political and ideological agenda” to serve on the nonpartisan board. “This is probably the most crucial school board election ever in Blue Valley,” Kessinger told The Star. Spending was more closely matched in the northwest district, with incumbent Hurley raising $3,400, compared to Hamilton’s $3,200. Incumbent Kessinger, a former Republican state representative running for the northeast area seat, reported more than $10,000 in contributions in August, compared to the more than $1,200 raised by opponent Vasquez, for example. The moderate slate, made up of two Republicans and two Democrats, has outspent the conservative group overall. There is no evidence that it is being taught in Kansas K-12 schools. Voters recently received a mailer advocating for the conservative candidates, paid for by the 1776 Project PAC, a New York-based political action committee targeting local school board races, that is aimed at abolishing critical race theory, a college-level framework for evaluating the impacts of racism on institutions. Voters across Blue Valley will elect a new at-large member, while incumbents are facing challengers for three district seats. 7 have divided themselves up into two clear factions.

A Short History of GMTĪfter all, this is precisely what GMT is: an agreement. It’s weird to think that the sun is only rising in Mumbai and is already at noon in Kolkata, but both cities agree it’s 9am as per India’s one time zone policy – but then, perhaps even time keeping can be an agreement rather than objective reality. It’s the same with China: although its territory is massive and easily hosts at least three or four time zones, the entire country observes only one – Beijing – time. For example, India spans a vast territory with several time zones in the geographical sense, but ever since the colonial era, the country observes only one single time zone from border to border. Funnily enough, while time zones are technically strictly defined by geography, it can sometimes be a purely political decision. Once again, this has to do with the rotation of the Earth: noon is noon from North to South, because the poles do not move West to East, however, sees a difference as the Earth turns around its own axis. That is, a time zone will cover the same countries vertically, which is why the UK and South Africa observe the same time. It’s sometimes confusing to think that several countries around the world can share the time zone, but a simple way of understanding it is this: time zones are defined by degrees East or West rather than degrees South or North. During summer, the UK is in the BST (British Standard Time) time zone. In other words, the country that invented GMT is not in GMT time all year round. In fact, even the United Kingdom is observing Daylight Saving Time during the summer months. Some countries are observing Daylight Saving time, so they are in the GMT+1 time zone during the warm months of the year. However, this does not mean that all countries in the GMT time zone have the same hour. In other words, Greenwich Mean Time has no UTC offset. For several centuries, GMT was used as both the time standard and a time zone, but it’s not the same as UTC: nowadays, GMT is firmly considered a time zone, and UTC is a time standard. At the center of GMT is the Royal Observatory in Greenwich, London, which sits on the Greenwich Meridian, or longitude zero. Greenwich Mean Time, abbreviated GMT, is a time zone that covers parts of Europe, Africa and Antarctica. However, you’ve probably also noticed the same time zones referred to as GMT -5 or GMT+5, and it’s equally correct… or is it? If UTC is a time standard, and GMT is a time zone, why the confusion, and why is UTC and GMT used interchangeably? Let’s take a closer look at GMT to figure it out. As an example, Eastern Standard Time (New York Time) is UTC-5, meaning it’s five hours behind UTC, whereas time in Central Asia will be at UTC+5 – that is, five hours ahead. The UTC standard monitors atomic time and is always at the “zero” hour anything West of UTC will have a minus offset, and anything East of it will have a positive offset (that’s why you hear time being “behind” or “ahead” when you’re looking at different time zones around the world). Each of these slices is a time zone, and each is coordinated using the Coordinated Universal Time (UTC) standard. This happened in the late nineteenth century when a Scottish-Canadian engineer and inventor Sandford Fleming proposed dividing the Earth into 24 slices of 15 degrees each. Midday in Hawaii will occur at a different time than in Moscow precisely because of the rotation of the Earth, so to make sense of time around the world and to calculate what time is it where, time zones were introduced. You know that most countries around the world have their own time zone, but you’re not sure why? There’s a simple explanation: Earth rotates by 15 degrees every hour, and that means that noon hits different places of the planet at different times. Ready to get your time right? Let’s dig right in: What Are Time Zones Exactly? And if you’re here for some fascinating time zone trivia, be sure to read the entire article – we’ve listed some fun time zone facts at the bottom of the page. To clear it up, let’s talk about time zones, UTC, UTC offset, and the GMT time zone specifically: after all, time is precious, and understanding time zones can save you a lot of stress and hassle if you work or communicate with people around the world. Curiously enough, the history of using GMT and UTC is intertwined, and it’s no wonder it’s still causing confusion. Why? While both terms are used to define the “zero” hour on which the time zone calculations around the world are based, there is one big difference between GMT and UTC – and that is, one is a time zone and the other is a time standard. However, you’ve probably also heard of UTC, and often, GMT and UTC are confused. Like most people, you’ve probably heard of GMT, or the Greenwhich Mean Time, and you know it’s used to refer to a time zone.
