The man accused of fatally stabbing his Kitchener girlfriend has had his extradition hearing postponed to October.

Ager Hasan, 24, of Hamilton was due to go before a Texas judge on Monday, but CBC News has learned that has now been pushed back to Oct. 6 at 1 p.m.

The change appears on the court docket for the San Antonio courthouse and says only that the date was reset because of a government motion.

Hasan was wanted on a Canada-wide warrant for the death of 22-year-old Vasilije. He is facing a second-degree murder charge in her death.

Vasilije was found dead in her apartment on Country Hill Drive at 3 a.m. on April 28. Hasan was seen crossing the border on the Peace Bridge from Fort Erie, Ont., to Buffalo, N.Y., around 6 a.m. on April 28 driving a black Honda HR-V.

A man matching his description was spotted switching licence plates off a vehicle in a Walmart parking lot in Harborcreek Township, near Erie, Pa., around 10 a.m. that same day.

It's believed the man put the stolen plates on his own vehicle and fled the area.

Online postings, emails to police

He became known for taking to social media while on the run — including posting a version of the events of the morning Vasilije died on Reddit, and also posting to Instagram.

Hasan was also in contact with investigators through email and Whatsapp and court documents obtained by CBC News said he asked police to give him a plea deal and he would turn himself in.

Police said the two had been in a relationship and the court documents showed Hasan "had difficulty accepting" the end of a year-long relationship and Vasilije "was nervous" about being alone with him.
