A Canadian national who was in the custody of the U.S. Immigration and Customs Enforcement died Saturday at Memorial Hermann Northeast Hospital in Humble.

Peter George Rockwell, 46, had been in ICE custody since Jan. 30. It is reported that he may have died due to a massive heart attack or stroke.

Rockwell, a legal permanent U.S. resident since 1993, was convicted in July 2013 on two counts of felony evading arrest and sentenced to three years of community service.

ICE was alerted on Jan. 29 by Canadian authorities that Rockwell was wanted on outstanding charges in Canada for 2003 charges of personation with intent, forged documents, fraud, spousal assault, breach recognizance and failure to appear. Rockwell was then issued notice to appear in immigration court on Jan. 30.

Rockwell collapsed while at ICE's Houston Contract Detention Facility and was rushed to the hospital on Feb. 15. He was placed on life support.

Rockwell was pronounced dead after his family authorized his removal from the life support.
