(ROUGH CUT - NO REPORTER NARRATION) The husband and stepdaughter of Jacquelyn Smith, the woman killed after her husband said she was murdered while giving out money to a panhandler from her car window, have been arrested for her death, police said Sunday (March 3) in a press conference.

Keith Smith, Jacquelyn's husband, and Valeria Smith, her stepdaughter, were arrested by Texas state police in Harlingen, near the Mexican border while trying to leave the country, CBS-affiliate WJZ reported the acting Baltimore police commissioner Michael Harrison as saying.

According to WJZ, Smith's husband claimed she was stabbed while she was helping a panhandler.

WJZ also said police had previously said they believe she was giving cash to a woman asking for money to feed her baby, when a man approached the car window, pulled out a knife, stabbed her in the chest, and robbed her.

"The information and the evidence points to it was not a panhandler, and people should still take caution and use due diligence when doing anything like that anywhere they are in America, but it points to the fact that it was not a panhandler and that the circumstances were very different and people took advantage of Baltimore, and what we want to make sure is that the truth comes out and justice is served," Harrison said.

Warrants charging them with first-degree murder were issued Sunday, WJZ reported Harrison as saying.

There is no word on when the two suspects will be extradited.
