A teen angry that a drug dealer tried to dupe him with fake marijuana — a bag of paprika, salt, pepper and other spices — shot the 19-year-old several times in his bedroom as his girlfriend looked on, according a newly unsealed search warrant affidavit.

Seth Carreras, 17, is facing first-degree murder charges as an adult in Utah in connection to the Nov. 21 shooting death of Hunter Woodson. The two had been messaging earlier that day about Woodson selling Carreras pot, his girlfriend told police, the Salt Lake Tribune reports.

Carreras agreed to go to Woodson’s home in Sunset, where the two smoked a joint so Carreras could test out the product, according to the affidavit. Carreras, who wanted to buy 1.5 ounces of the drug, didn’t have the necessary cash on him, so he returned home, but later agreed to pay $121 for the sale.

When Carreras returned later that day, Woodson told his girlfriend to go outside to get the money while he poured a mixture of spices, including paprika, salt, pepper and other kitchen herbs, into a pink bag before tightly taping it up, according to the affidavit.

But Carreras quickly realized something was off after feeling the bag, prompting Woodson’s girlfriend to run back into the home to warn Woodson, who then ran into his bedroom with her.

Carerras then fired a 9mm handgun at Woodson “a lot of times,” sending him to the floor. Carreras stood over Woodson and continued to shoot, his girlfriend told investigators. Carreras also went through Woodson’s pockets as his girlfriend ran out of the room, she said.

Carreras was arrested at his home in Layton less than 30 minutes after Woodson’s girlfriend called police, KSL reports. A total of seven shell casings were recovered by police inside Woodson’s home, where his girlfriend said Carreras just “kept shooting,” according to the affidavit.

Carreras was also charged in December with assault by a prisoner while being held at the Farmington Bay Juvenile Detention Center, where he allegedly kicked a staffer. Carreras was scheduled to appear in court on both charges Friday, according to the station.
