Two teenagers charged with shooting Family Dollar manager Wally Knapton to death during a store robbery that netted $180 made their first appearance in court Tuesday.

Biu Benjamin Olive, 18, is charged with aggravated murder and two counts of aggravated robbery, all first-degree felonies. He also is charged with second-degree felony obstruction of justice.

Sarah Ataata, 19, whom police believe drove the get-away car, is charged with murder and two counts of aggravated robbery, all first-degree felonies.

Both appeared before 3rd District Judge Randall Skanchy, who appointed legal defenders for each.

Skanchy set a scheduling conference for the pair on April 7 before 3rd District Judge Vernice Trease.

Prosecutors believe Olive was the gunman in this case. Ordinarily, prosecutors can seek the death penalty in aggravated murder cases that involve adult defendants. However, Olive does not come under that category since he was a few days shy of his 18th birthday when the store shooting occurred.

If convicted on the aggravated murder charge, the toughest sentence Olive could face is life in prison without parole.

A 13-year-old boy also has been charged, but his case will be handled in juvenile court.

Court documents say Olive, armed with a .22 caliber rifle, and the 13-year-old went into the Family Dollar store in Glendale on March 12, robbed a customer and demanded that a store worker give them money from the cash register.

Knapton came to the front of the store to see what was going on and Olive shot him once in the chest, according to court documents. Olive then grabbed the cash register's drawer, the two males ran to the get-away car, and all three ended up splitting the cash from the robbery, which totalled about $180, according to court documents.

A in-store surveillance video camera captured what happened.

Olive is being held in the Salt Lake County Jail on $1 million cash-only bail. Ataata is being held on $500,000 cash-only bail.
