PEORIA, AZ (3TV/CBS 5) -

Police have located and detained the suspect in a stabbing that left one man dead Saturday afternoon. 

Peoria police say officers responded to a stabbing call near  67th Avenue and El Cortez, which is near Happy Valley Road at around 2:45 p.m.

According to court documents, the mother of the suspect, 30-year-old Anthony Paul Kupreisis, called 911 after she heard an altercation between him and her boyfriend who is the victim.

She found the vicitm, 57-year-old Jeffrey Falesch, with what documents say was a hunting knife still embedded in his sternum.

Kupreisis had fled the scene by the time officers arrived. Falesch was taken to a local hospital where he died of his injuries.

Police put out an alert on Kupreisis and the vehicle he was driving. He was believed to be headed toward California.

Peoria police said Sunday morning that U.S. border patrol agents found Kupreisis at around 11:15 p.m. Saturday night at a checkpoint on Interstate 8 in Yuma County. 

Documents state that Kupreisis had 17.5 grams of marijuana inside his vehicle. 

He was taken into custody and interviewed by detectives where he admitted to stabbing the victim.

Documents state that Kupreisis made repeated statements that 'everyone was out to get him' and that he had a 'feeling' the victim was trying to kill both him and his mother. 

Kupreisis was booked on one count of first-degree murder and was transported back to the Valley after the Christmas holiday.

Peoria PD said the investigation is ongoing.
