PHOENIX - Police say 27-year-old Andrew Ward is in custody after stabbing his 12-year-old half-brother to death Wednesday night in north Phoenix.
Phoenix police said the homicide occurred around 6:30 p.m. in a residential area near 35th Avenue and Deer Valley Road.
When officers arrived at the home, they found 12-year-old Austin Tapia with multiple stab wounds.
When paramedics arrived, they tried to save the boy, but his injuries were too severe.
Police said the boy's mother and sisters were at dinner when the incident occurred and arrived home to find police on scene.
Detectives interviewed Ward about the crime.
When asked why he killed his brother, he reportedly said, “Honestly I just felt like killing."
Police told ABC15 the suspect called 911 from a nearby convenience store to report the crime.
Kristina Krasovich was on a break from her job at the Circle K when she says the suspect came up to her asking to use her cellphone.
She said he was one of her regular customers who often came into the store with his little brother and had just been to the store by himself 15 minutes earlier.
Krasovich said this time she noticed his arm was covered in blood, as well as his shirt and it looked like he had wiped his hands on his pants.
“He was real shaky and scared. I could see in his eyes something bad had happened,” Krasovich said.
According to court documents released Thursday, police found a knife in Ward's pocket when they took him into custody.
Ward's family reportedly told police the suspect does have depression issues, but mainly has issues with drugs and a history of domestic violence and threats against them.
Deer Valley Unified School District officials confirmed to ABC15 the boy was a 6th grade student at Paseo Hills School.
School officials said the school is working to have a team of counselors ready to speak to staff and students.
Officials said the principal would send out a phone notification Thursday and post a letter to the school's website.
