MINOT (AP) - A man accused of fatally shooting the mother of his child in Minot early this year has been ordered held without bond.

Judge Douglas Mattson on Tuesday granted Ward County State's Attorney Roza Larson's request not to allow 27-year-old Omar Kalmio to go free on bond because she said he's a flight risk because he's not a U.S. citizen and because he has a violent past.

Kalmio is charged with murdering 19-year-old Sabrina Zephier and is due back in court Sept. 15 to enter a plea.

Mattson ordered a public defender be assigned to represent Kalmio, who faces up to life in prison if convicted.

Zephier's body was found in her apartment the same day her brother, mother and mother's boyfriend were found slain in a nearby mobile home. Police said last week they are still investigating the other three slayings.

Kalmio, who is from Somalia, has been transferred to a jail in Minot from one in Grand Forks, where he had been held since February for an alleged immigration violation stemming from a 2006 conviction in a Minneapolis stabbing.

Police contend in court documents that a witness claimed Kalmio and Zephier argued, and that they had an argument days before she was killed. Kalmio's co-workers at an oil rig site near Williston told investigators that Kalmio had allegedly made statements about Zephier getting pregnant on purpose and ruining his life. Authorities say Kalmio also allegedly described injuries to Zephier that had not been publicly disclosed.

The couple's infant child was found alive in the apartment where Zephier's body was found.

The Zephiers were members of South Dakota's Yankton Sioux Tribe.
