Phoenix police have made an arrest in the stabbing death of a man on Christmas Day.
Alexander James Chavez, 26, was arrested on Jan. 6 and booked into jail under suspicion of second-degree murder, according to Phoenix police officer James Holmes.
He did not make any statements to police during or after the arrest, said police.
The investigation began on Dec. 25, 2015 when a man, later identified as Isaac Rivera, was dropped off at Banner Estrella Hospital with a stab wound. Rivera later succumbed to his injuries.
Police have determined that Rivera rode his bike to a Circle K near 83rd Avenue and Thomas Road and then went to a home near 79th Avenue and Thomas.
While at the home, Rivera and Chavez got into an argument where Chavez allegedly stabbed the victim.
Police have not yet determined what the two were fighting about. They also do not have a lot of information to go on regarding the investigation, said Holmes.
Detectives have searched the area between Rivera's home and the Circle K for a crime scene, but did not find one. They've also investigated Rivera's bike and have found nothing either.
Police are asking the public for help. Anyone with information is asked to call Silent Witness at 480-WITNESS.
"It's the worst call a parent can get," said Emma Radzinski, Rivera's mother.
Isaac Rivera leaves behind a fiance and two children.
The family has set up a GoFundMe account for anyone who wishes to help with funeral expenses.
