Teen Charged With Killing Grandma

ROSEVILLE, MN — A 17-year-old from Roseville faces assault and murder charges in the killing of his grandmother and the attack on his mom and sister.

Matthew Francis Hill was charged through a juvenile petition with two counts of first-degree assault and one count of murder. He attacked the family members he lived with in Roseville, authorities said.

The incident Tuesday prompted Ramsey County to issue a shelter-in-place alert to cell phones in a small part of Roseville. However, the alert was mistakenly sent to phones across the Twin Cities metro area.

The juvenile petition identified three family members who survived by their initials:

"M.P.H." — Hill's 55-year-old mother, who suffered serious injuries.

"B.B.H." — Hill's 20-year-old sister, suffered minor injuries.

"A.J.H." — Hill's 23-year-old sister, who suffered serious injuries

Hill's father and brother were at work during the attack, police said.

On Tuesday just before 10:30 a.m, Roseville police responded to a home on Ryan Avenue West on a report of a domestic assault.

The 911 caller reported her brother, Hill, "went crazy" and attacked family members before fleeing the house, according to authorities.

Police said they found Hill’s grandmother was found lying in a bed on the first floor of the home, covered in blood with "obvious puncture wounds to her neck."

There was a knife on the grandmother's chest, and she was unresponsible but had a faint pulse, according to authorities.

By the time Allina medics arrived on the scene, her pulse faded away and she was declared dead, police said.

Detectives found a bloody black aluminum baseball bat inside the front door, according to police.

A.J.H. told officers she was sleeping in her room when she awoke to the sound of her mother and brother yelling in her grandmother’s bedroom, according to authorities.

A.J.H. went to see what was going on and Hill attacked her with a metal baseball bat, according to the petition.

A.J.H. tried to wrestle the bat away from Hill, and he dropped the bat, authorities said.

A.J.H. then picked up the bat and clubbed Hill over the head, the petition said.

A.J.H. yelled at Hill, and he eventually did flee the home, the petition said.

M.P.H. told police she was upstairs in the home when she heard Patricia ring the bell she uses when she needs assistance. Hill attacked M.P.H. in Patricia's bedroom, according to police.

M.P.H. — who was interviewed at the hospital and had trouble communicating — said she thought Patricia was already dead by the time she got into the bedroom, according to authorities.

Hill had a blank stare and was not speaking to anyone during the attacks, police said.

The serious injuries to the mother and A.J.H. will cause "permanent disfigurement," a Regions Hospital nurse told police.

St. Paul police found Hill, bloodied, walking on Stella Street towards Como Avenue just after 11 a.m., according to authorities.

He was arrested without incident, police said.

Officers noted "Hill’s eyes were wide open and glazed over, and he was seemingly unable to verbally communicate," the petition reads. Hill moved his body very little during the hours-long interview, according to a detective.

Hill told the detective he felt like he was "going crazy" and "being someone else," according to police.

Hill said he did not know who he was, authorities said.

According to police, when asked if he felt that someone else was using his body to kill, Hill replied '"I’d like to say that it is not me. I’m not very sure who me is."

Asked if he felt responsible, Hill replied, "I think I have to be," according to authorities.
