HELENA — A Helena woman convicted by a jury of participating in an armed home invasion to rob a couple involved in trafficking heroin was sentenced Thursday to one year and one day in prison and three years of supervised release, U.S. Attorney Kurt Alme said.
After a three-day trial in February, a jury found Arielle Rose Cowser, 27, guilty of conspiracy to commit robbery affecting commerce and robbery affecting commerce.
In evidence presented at trial, the prosecution said the FBI learned of a home invasion robbery in Helena in which the victims, a couple, were involved in trafficking heroin.
Co-defendant Kielan Brett Franklin, who pleaded guilty and is pending sentencing, provided the couple money to travel to Washington to buy an ounce of heroin. The couple returned to Montana with less than an ounce. When the couple did not immediately turn over the heroin, Franklin sent them threatening text messages.
On March 8, 2019, Cowser went to the victims’ residence and asked to enter, saying she had broken up with Franklin. The female victim let Cowser inside and a few minutes later, Cowser let in Franklin and two other co-defendants, Gerald Allen Hiler and Morgan Victor Pitsch. Hiler and Pitsch, who also pleaded guilty, wore masks. Hiler was sentenced to 11 years and seven months in prison, while Pitsch was sentenced to six years and six months in prison.
Hiler brandished a handgun and Pitsch possessed one during the robbery. The defendants fled when they realized the female victim had called 911. The robbers took a small amount of heroin, the female victim’s wedding ring, her cell phone and a purse.
Assistant U.S. Attorneys Tom Bartleson and Tim Racicot prosecuted the case, which was investigated by FBI, Montana Regional Violent Crime Task Force, Lewis and Clark County Sheriff’s Office and Missouri River Drug Task Force.
