shootings. one of the victims who died, 14-year-old davon day artis, was working home from school. >> he was coming home from school actually, getting off the w-4 bus, walking through that way to come home, to come down here. he lives at the bottom of the hill, so that's how he got caught up in it. wasn't meant for him at all. >> the other victim killed in the shootout has been identified as

county planning commission agreed with residents and denied the church's application. a spokesperson for the church says they feel their religious rights have been violated. they plan to pray about what to do next, which could include an appealr legal action. also new today comes word that despite the rising stock market the number of home foreclosures continues to rise. new data shows 938,000

while virginia students stayed about the same. we're joined by tracee wilkins, who's live outside meyer elementary school in washington. tell us the good news. >> reporter: barbara, i love good news for d.c. schools. don't we all? it's rare we get the opportunity to share some of it. it's been a struggling school system for some time now, but, yes, it looks like d.c. school students in math have achieved mo gains than students across the nation so fourth grateders here at meyer and other elementary schools across the district and also eighth graders have a lot to be proud of. looking at all the significant gains they have made. it's considered one of the nation's poorest performing school systems, but charter and public school students rose five points in fourth grade and six points in eighth grade in d.c. this is based on a 500-point scale test. the test, which is taken every two years, is called the national assessment of educational progress. it's considered the nation's report card, and again taken every two years. maryland also showed some gains but scores in virginia remained stagnant. in fact, scores around the country remained flat, worrying some school reformists who want to see higher scores in math for u.s. students. this is about competing on the national world stage and making sure that we are as viable as possible in mathematics and that our students are doing well. d.c. is an elite line of schools here, school systems across the country because only four other states had significant gains and that was in nevada, new hampshire, rhode island and vermont. d.c. schools spoke men say they have added teachers to the school and specialists to work with students as well. they're hoping that's what made the difference. back to you in the studio. >>

still don't want to get vaccinated. tests are still under way, so safety is a concern for some. but government officials and ethics experts are doing their best to re-assure the public. >> what kind of an example is this to set in the middle of flu season and the possibility of swine flu epidemic to say nurses, doctors are not going to take these vaccines? >> a decision to wait is not risk-free. it is possible that you or your child will get influenza in the waiting period. >> meanwhile, colleges are still being hit hard by the virus. the american college association reports 6,000 new swine

adults at this particular clinic, and again they will be offering both the shots as well as the nasal form of the vaccine. now, this clinic is free and it's open to the public on a first come, first serve basis. we have been seeing quite a demand here for the vaccine. yesterday at a clinic in montgomery county there was an enormous line with people waiting as long as two hours in order to get their vaccination. so we're expecting possibly a very large crowd here at this clinic today as well. let's take a look at the exact location here. this is being held at the spring hill lake elementary school in greenbelt. gets under way at noon and will last until 4:00. they are going to be targeting adults in this clinic, specifically pregnant women, young adults 18 to 24 as well as caretakers of

going to then happen every thursday after that, they'll have a clinic every thursday after the 22nd at the prince george's county health department where the general public can then go and get their vaccinations. but right now they are targeting specific groups, pregnant women, people with underlying health conditions and that sort of thing. again, the clinic here in greenbelt open to the public, gets under way at noon. barbara, back to you. >> okay. thank you, megan. the universityf maryland is conducting a mass flu vaccination event in college park this afternoon. about 2,000 students,

topic on his radio show this morning. tom joiner's uncle's pardon nearly a century after their execution. thomas and meeks griffin were electrocuted in 1915 for the murder of a wealthy confederate army veteran. immediately doubts surfaced about their guilt. yesterday, they were pardoned. joiner learned about the execution two years ago, and set out to clear their names. >> even though they're not here, this won't bring them back, but this will bring closure, and so i hope -- i hope now they rest in peace. >> joiner's uncles were apparently given just 24 hours to get their defense together.

question now, if and when chris samuels will return. the six-time pro bowler got hurt early in the panthers game. the injury didn't look that bad, but samuels jammed his neck. for him, it's more serious because he has stenosis, which is the narrowing of the spine, a very dangerous condition for anyone, but especially when it involves violent, head-on collisions. one has to wonder if chris samuels' career might be over. let's hope not. that's your sports minute. i'm dan hellie. everybody have a great day. >> the north pole may turn into an open sea during summer months within a dede.
