He works for the Nebraska Humane Society, but Thursday night he was an author.
Hundreds showed up to Mark Langan's book signing party. His name might sound familiar. WOWT 6 News has done stories with him in the past involving animal cruety cases.
Langan says he is so proud to have published his book, "Busting Bad Guys."
"We really treated a lot of stories with respect," said Langan. "Stories about kids suffering unbelievable conditions. People dying in horrendous situations. But then I wrote funny stories too. So, I really tried writing the stories with respect for everyone involved."
The e-book version will be available Monday.
