Here is a news about a recent rock believed to have come from Mars. Scientists are very excited because this rock just dropped to Earth recently making it a fresh sample. But more interestingly is the comment at the end of this article - here is what is says about the once popular theory that life came from Mars via meteorites.
"A Martian meteorite that was buried in Antarctica made news in 1996. NASA scientists theorized the rock showed traces of life from Mars. Even the White House declared it the first sign of life outside of Earth. Years of study since then have led much of the astronomy world to conclude there was insufficient evidence to support the claim."
