On Friday Kennedy Brewer was exonerated for the rape and murder of a three-year-old that he was convicted of in 1995. His release came after DNA testing proved his innocence.

"There are people in prison who don't need to be there. Hopefully there are very few people like that. Particularly when the stakes are high, like if it is a death row sort of thing, obviously you want to do everything you can to make sure the right person is convicted," said Rep. Greg Snowden - Republican, Mississippi District 83.

The DNA testing in Brewer's case came after the Innocence Project aided his attorneys. The group says that Mississippi needs to make changes to the laws to better protect the innocent.

"The Innocence Project has asked for certain legislation. I know that they are concerned that the evidence is preserved because obviously if you have someone after the fact, the only way to prove their innocence is if you have the evidence and that's a reasonable thing to want to do," said Snowden.

Snowden says a bill came about in a subcommittee earlier this session, but it was not brought forward because it was too broad. The bill required all law enforcement agencies in the state to retain all evidence in felony cases until the statute of limitations had passed.

"I think there will be a struggle, if you will, to try to find the right formula for preserving evidence we need to preserve without overburdening the system any more than it already is."

Snowden says there is answer out there and he hopes the legislature can find it.
