Police say further investigation revealed Pena was inside his truck when he was shot in the back of the head. DNA evidence linked Holland and Cook to the truck, booking records show.

Investigators also found a cell phone in Pena's possession when he died and a collection of text messages that described a meetup for a suspected narcotics transaction, according to booking documents. 

Robinson's phone matched the number of the person Pena had been texting, leading investigators to determine Robinson had lured Pena to where he was killed, documents say. Pena arrived under the impression he would buy $1,800 worth of narcotics. 

Holland played football for McNeese and Tulane University prior to signing as an undrafted free agent for the Tampa Bay Buccaneers in 2011. He later signed a contract with the Washington Redskins but was released in 2013, according to NFL records.
