Police confirmed they have arrested the man suspected of stabbing his pregnant Bedford roommate to death.
Lt. David Smith of the Bedford Police Department confirmed to NBC 5's Jeff Smith that Robert Atlas had been arrested at a Wal-Mart parking lot near Shreveport, La., around 2 a.m.
Atlas is suspected in the fatal stabbing of his pregnant roommate, Tracy Anderson, who police said had a romantic history with Atlas.
"There's no reasonable explanation. It's hard to fathom." Smith said about the murder. "You don't want to see it occur, but when it does happen, you're glad to catch the person alleged to have done it so quickly."
Smith said Bedford police got an anonymous tip from someone who knew Atlas that said Atlas wanted to turn himself in, but didn't know where to go or what to do.
After Atlas' arrest, he was taken to a Louisiana jail. Police have not decided when Atlas will be extradited to Bedford.
"Once he's arraigned, we'll determine when we're going to go down there and get him," Smith said.
Bedford police found Anderson's body around 1:40 p.m. Sunday in an apartment she shared with Atlas.
Police said Anderson had been stabbed multiple times. Officers also said it appears the apartment had been entered by force.
Bedford police had been searching for Atlas since Sunday, at first saying they were concerned about his safety.
As the investigation continued, police eventually named Atlas as a suspect in Anderson's murder and a judge issued a capital murder warrant for his arrest on Monday.
Atlas and Anderson were described by police as having an on-again, off-again relationship. It was unclear whether Anderson and Atlas were in a romantic relationship as of when the pair moved in together in the Bedford apartment about three weeks ago.
Police said Anderson was pregnant and that family members told investigators she was in her third trimester. The exact length of the pregnancy is still being determined by the Tarrant County medical examiner in order to determine if additional charges would be filed against Atlas.
A photo posted to Anderson's Facebook page contained a comment from Anderson that claimed Atlas was the father of the baby and that her due date was set for May 16. That information has not been confirmed by medical professionals.
