DES MOINES, Iowa -- A Des Moines teenager accused of beating his grandmother to death was moved to the Polk County Jail on Tuesday.
Polk County Sgt. Brandon Bracelin said Noah Laprei was moved from the Marshal County Jail to Polk County on his 18th birthday.
Bracelin said the Polk County Jail utilizes the Marshal County Jail to house juveniles in custody.
Laprei pleaded not guilty to first-degree murder in the October 2015 death of his grandmother, Rachel Pray. Police say Laprei, then 17, beat his grandmother to death in the home they shared. The teen's family said he was on drugs at the time.
Laprei was arrested the same night at a nearby gas station. Security video shows Laprei carrying a Bible, knocking over shelves and hitting a customer at the gas station.
In December, a judged delayed Laprei's trial from January to May. He is currently in the Polk County Jail on $500,000 cash bond.
