4. He also was a professor at Delta State. He reportedly taught geography and social-science education courses at the college, where he began working in 2009, the AP reports. This semester, he was teaching two online classes, Delta State officials told the AP. 

Lamb previously worked at Mississippi Valley State University, Riverside High School in Avon, Murrah High School in Jackson and Greenville-Weston High School in Greenville, WMC reports.

5. Lamb's friends and acquaintances were shocked by the news that he was a suspect in the case. "I couldn't even imagine what would be going through his head to cause something like this," friend Eddie Dixon told WMC. "Whatever it was, it had to be very drastic."

Delta State student Noah York told WMC that he met Lamb, who played guitar and harmonica, last year at a party. "He was a cool dude. I mean, you never would have thought anything like this would happen," York said, according to CNN.
