HARRIS COUNTY, Texas -

The Harris County District Attorney's Office says two people have been arrested in connection with a deadly dog attack that happened back in January.

On Tuesday, D.A. Devon Anderson announced that Timothy Dewayne Coleman and Tiara Deshawn Thomas were charged with dog attack after two pit bulls killed a 43-year-old woman named Christina Burleson on Jan. 5.

"We used to have to show that an owner knew a dog was dangerous. Now we have to show that the owner is not securing the animal which we were able to do in this case," said Anderson. "We have evidence that the dog had killed another dog and been involved in two other attacks against people. So this is a case where we're frankly going to make an example of these two owners. We like dogs. I have a dog. But as a pet owner, you have to be responsible."

Witnesses say the dogs attacked Burleson in the 7600 block of Glen Prairie. HPD investigators say at least one of the pit bulls belonged to Coleman and Thomas.

Anderson says a second dog as also involved in the attack but was never located.

"Many people believe their dog is a loving member of their family and will not bite, but given the right situation most dogs can attack. You must be a responsible pet owner," said Anderson. "Sadly, Christina's life could not be saved, but we haven't forgotten her and we are seeking justice in this horrible case."

If convicted, Coleman and Thomas could face two to 20 years in prison and up to a $10,000 fine.
