Federal agents did not have body-worn cameras when a U.S. Immigration and Customs Enforcement officer fatally shot a Mexican homebuilder who was driving a work van they tried pulling over in Houston, the Department of Homeland Security said Thursday.

Separately, prosecutors in Houston said they are investigating the death of Lorenzo Salgado Araujo, whose family has joined Democrats in calling for an independent probe over Tuesday's early morning shooting in one of the city's heavily Hispanic neighborhoods.

Few photos or videos surrounding the shooting have emerged publicly in the days since the encounter between Salgado Araujo and ICE agents, unlike other deaths involving federal immigration officers.
