[Essential California]( Essential California [Send to friend](mailto:?subject=Essential California: The pitfalls of DNA testing&body= | [Open in browser]( Presented by* [L.A. Times Food Bowl]( Good morning, and welcome to the [Essential California newsletter](. It’s Friday, May 4, and here’s what’s happening across California: TOP STORIES There were failed leads that came before last week’s dramatic capture of Golden State Killer suspect Joseph James DeAngelo Jr. in a Sacramento suburb — an arrest that also hinged on the novel tactic of comparing crime scene DNA with genealogy site data. Though prosecutors are sure they have the killer, their earlier probes illustrate the potential pitfalls of a strategy that relies on a fishing expedition to identify potential suspects in a sea of genetic data. By casting such a wide net, authorities risk compromising the privacy of anyone whose genetic data appears online, along with their relatives, experts say. [Los Angeles Times]( — A Sacramento County judge on Thursday ruled that the Golden State Killer suspect cannot refuse to provide additional DNA samples, fingerprints and photographs of his body sought by authorities as part of their investigation. [Los Angeles Times]( — How the Golden State Killer case has some of its roots in another murder mystery in New Hampshire. [New York Times]( Expelled The motion picture academy announced Thursday that it has expelled comedian Bill Cosby and director Roman Polanski from the group’s ranks as the organization struggles to deal with #MeToo. In response to unfolding sexual misconduct charges against film mogul Harvey Weinstein, the academy had earlier expelled Weinstein and announced it would adopt new standards of ethical conduct that its members would be expected to uphold. How exactly those standards will be enforced has been the subject of some debate. [Los Angeles Times]( Off to Mars For decades, earthlings have dispatched spacecraft to Mars to study the planet’s dusty surface and its thin atmosphere. Now NASA is sending a lander to the red planet to look deep into its heart. As early as Saturday morning, NASA’s InSight will blast off from Vandenberg Air Force Base. After a nearly seven-month journey, it will begin probing the deep interior of a nearby world that once may have looked much more like our own.

For nearly 50 years, the University of California and Berkeley activists have been locked in conflict over one of the state’s most contested pieces of land. The standoff dates to 1969, when hundreds of people hauled sod, trees and flowers to a scruffy lot that the university intended to build on and proclaimed it their own People’s Park. Now, UC Berkeley officials hope they finally have a plan that will let them use the space without fierce backlash.

[More weather is here.]( AND FINALLY Today’s California memory comes from Patric Barry: “In 1973, I was coming through LAX from Australia, and I looked down on approach and saw the brown air hanging over the city. Brown, yuck. I wondered why people chose to live in the place. I then had eight hours to kill, so I took a bus to downtown and saw freeways and discouraging things near the bus terminal. Same back to LAX. A year later I was back in Los Angeles, and I learned to fly, and I flew in the brown air. It smelled like a mix of diesel and cigar smoke at 3,000 feet. Now it’s clean. No smell. Life is better. I’m still here. I love L.A.” If you have a memory or story about the Golden State, share it with us.
