A North Platte man who spent more than a decade in prison for killing an 18-year-old girl is now facing several drug charges. North Platte Police arrested 29-year-old Tyler Keup on Sunday on suspicion of helping distribute methamphetamine. Keup faces additional charges because he was carrying a knife, marijuana and some Adderall. Keup was released from prison in 2011 after an appeal because he was 16 when he shot Maricella Martinez and the judge ruled he couldn't form the intent to kill. He was originally sentenced to 30-60 years. Keup remains jailed Tuesday on $250,000 bond. A 30-year-old woman who was riding in Keup's car is also facing charges because she had drug paraphernalia and a knife.
