A realtor in Dallas shot and killed in a parking lot as her horrified daughter watched was trying to sell the girl's iPhone to buyers they'd met on an app, according to a report Tuesday.

The shooting killed 42-year-old Martha Teran at a Medieval Times parking lot Sunday night, Fox 4 reported. A fellow realtor said Teran was new to the business and had planned to move to Louisiana to be closer to her common-law husband.

Teran's daughter had been trying to sell her iPhone 7 on an app known as OfferUp, relatives told WFAA. The people who claimed they were the buyers shot and killed the mother before escaping, the news station reported.

Family members told WFAA the three suspects had wanted to meet at a different location, but the mother refused. Relatives said there was "little to no communication" before they fired shots.

Police did not initially name any suspects.

"It's tragic news,” realtor Tom Gilchrist told the news station. “We're all shocked.”

The woman's family set up a GoFundMe page to raise money for funeral services.
