In Utah, a teenager with a history of running away is accused of fatally shooting his 15-year-old girlfriend in her home. Authorities allege that Hezekiah Plummer, 16, shot her in the head at close range.

Plummer faces charges as an adult, including first-degree murder, obstruction of justice, and theft of a firearm, related to the death of Chanelle Alvarez in Ogden. This information comes from a probable cause affidavit acquired by Law&Crime.

According to the affidavit, Plummer claimed a “robbery” took place at the residence after he arrived around 1 a.m., stating he had nowhere else to go.

The police report indicates that Alvarez allowed Plummer to stay at her home. A witness residing there recounted being awakened by gunshots around 3 a.m., which seemed alarmingly close.

Rushing to ensure his children’s safety, the witness reportedly encountered Plummer on the staircase with a firearm. Plummer allegedly mentioned a “robbery” and named someone he claimed attempted to rob them before fleeing the scene. Alvarez was later discovered shot downstairs.

Plummer made a statement about a “robbery” happening and mentioned a name of a person who he said “tried to rob them,” according to police. Plummer then fled the residence with the gun and Alvarez was found shot downstairs.

Police say the girl’s mother had purchased a Glock handgun “a few weeks prior” to the shooting, which Plummer allegedly swiped. The mom told investigators she was “awoken” by Plummer in the middle of the night before she left for work around 2:40 a.m., with him looking around her room for a “backpack” that he claimed to have left in there, the affidavit says.

“She indicated it was not in her bedroom and he left,” according to the charging document. “When she awoke to leave for work, Plummer and the victim were in the victim’s bedroom. They were the only ones in the bedroom.”

After the shooting, Alvarez’s mom allegedly found a box that had contained the Glock inside her daughter’s room and the firearm was missing.

“Plummer did not have permission to possess or take the firearm,” the affidavit says, noting how the obstruction of justice charge is related to Plummer allegedly disposing of it after the shooting. “Autopsy revealed that the victim sustained a single gunshot wound to the head and that there was stippling near the wound, indicating the shooter was in close range,” the document adds.

A GoFundMe that was launched for Alvarez’s family describes her death as being “the result of domestic violence,” with cops reporting in the affidavit that the two teens were boyfriend and girlfriend.

“Plummer was known to run away from home and he resided in the home with the victim for substantial periods of time,” police allege. “He kept at least some belongings in the home until he was last made to move out of the home a couple weeks prior.”

Authorities say they later found Plummer in Davis County in possession of several ounces of marijuana and $4,080 in cash, which also led to a drug charge. “Plummer declined to be interviewed by authorities and invoked his rights,” the affidavit says.

The teen is currently being held without bail.
