DALLAS (CBSDFW.COM) – So far police haven’t arrested any suspects in connection with the Wednesday morning murder of a Dallas couple.

Yayehyirad Lemma and Yenenesh Abayneh Desta owned a popular Ethiopian restaurant. Police say they found the couple shot to death on the doorstep of their home.

Investigators told CBS 11 News there was no obvious motive and nothing was taken from either victim — indicating robbery wasn’t the goal.

David Eseke rents an apartment from the couple and was asleep next-door early Wednesday, but said he didn’t hear the gunshots. Eseke thinks weather had something to do with that.

“There was a ton of lightning last night… thunder,” he said.

The couple owned Desta, an Ethiopian restaurant on Greenville Avenue.

Yayehyirad Lemma, who was 40-years-old, and 31-year-old Yenenesh Desta had a one and a half year old son together.

Grieving family members visited the couple’s home Wednesday and gathered at church to pray.

A friend described the pair as a, “very beautiful, down to earth couple.”

Lemma’s close friends said they have no idea why anyone would kill the pair.

A number restaurants owners near the Desta Ethiopian Restaurant closed Wednesday to honor the couple. Flowers were placed outside the door of the restaurant.

Police say the investigation into the shooting in the 5700 block of Marquita Avenue is ongoing.
