Nearly two years later   Bart Whitaker  was arrested in Mexico after investigators determined  he  arranged the plot in hopes of collecting a family estate  he  believed was worth more than $1 million.
“I’m 100 percent guilty ”  Whitaker  testified at  his  trial in 2007. “I put the plan in motion.”
 Whitaker ’s father said he loves and has forgiven his son  calling him a changed person.
The gunman  Chris Brashear  pleaded guilty in 2007 to a murder charge and is serving life in prison. Steve Champagne  who drove Brashear from the  Whitaker  house the night of the shootings  took a 15-year prison term in exchange for testifying at  Whitaker ’s trial.

Letitia Wright
 You may know  her  from: The AMC show âHumansâ and Decemberâs âBlack Mirrorâ finale on Netflix  âBlack Museumâ
Where youâll see  her  this year: Playing Princess Shuri  the half-sister of Chadwick Bosemanâs title character in the highly anticipated Marvel movie âBlack Panther â as well as in roles in Steven Spielbergâs âReady Player One â the Liam Neeson thriller âThe Commuterâ and as Shuri again in âAvengers: Infinity Warâ
Why  she âs a standout: A Londoner who was born in Guyana  the 24-year-old actress is a rare overtly religious Christian in Hollywood.  Wright  has said  she âs prioritized God over roles in the past: âI gave my life to Christ  and I thought that would be it for me  and  he  was like  âNo  youâre not finished with acting  acting is not finished with you ââ  she  told Womenâs Wear Daily.
 She  has also been an ardent advocate for more positive black roles in the film industry. âShuri is one of the most exciting characters Iâve been blessed to portray â  Wright  tells The Post. âIâm looking forward to the positive impact  her  love for technology and science will have on the younger generation. Being a part of the film feels kind of like history in the making!â
You may know  him  from:  His  breakout performance in the 2012 Matthew McConaughey indie âMudâ and  his  role as Cyclops in 2016âs âX-Men: Apocalypseâ
Where youâll see  him  this year: Starring in Steven Spielbergâs retro-tastic sci-fi thriller âReady Player Oneâ and the next X-Men movie  âDark Phoenixâ
Why  he âs a standout: Sheridan got  his  start working with auteur Terrence Malick on âTree of Lifeâ at the early age of 10  but  he  didnât go into the business a film-obsessed kid: âI grew up in the middle of Texas in a very rural area  so we were always outside fishing or playing a sport â we were never in front of a TV watching films â  he  told the Independent. The square-jawed  21-year-old actor brings an ease and authenticity to his roles that should make him the perfect centerpiece to Spielbergâs otherwise-highly-CGIâd film about virtual-reality gaming.

"The conventional approach to developing flu vaccines today is one in which we perform surveillance worldwide " said David Topham  director of the New York Influenza Center of Excellence and professor of microbiology and immunology at the University of Rochester in New York.
"We collect the viruses that are circulating in people " said  Topham  who was not involved in the new study . Those viruses then typically are studied in ferrets    he  said.
"We create an antigenic map of each virus and determine how similar or different that is than the (current) vaccine strain  and if it's different enough from the vaccine strain then we select that virus to be in  next year's vaccine " Topham  said. In other words  they make their best guess on what strains will be most likely to spread and cause illness based on surveillance data
On the other hand  the new study suggests "using high-throughput sequencing methods and genetic engineering to rationally design a virus to use as a vaccine "  he  said. "I thought it was a very innovative and comprehensive approach."
The new study acted like "rocket science" compared with the conventional approach used to develop flu vaccines   he  said.
So what does the future hold for flu vaccines and where could this new approach fit in? There has been a shift among researchers around the world to focus on developing universal vaccines   Topham  said.
"These  for influenza  would be vaccines that would last for at least five years and protect against 75% of the viruses that are out there "  he  said. "There are many ways that we might be able to achieve that. This approach that's described in this paper is just one approach."
