A man burned his mother, aunt and another woman by dousing them with gasoline and setting them on fire Wednesday, police said.

Waco police Sgt. Ryan Holt said Ishmael Reuben Lopez, 23, pulled a knife on his mother during an early morning argument at their home. When the other two women tried to stop Lopez, he retrieved a jug of gasoline, threw it on them and set them on fire, Holt said.

Lopez, who ran away and remained missing Wednesday afternoon, apparently was burned in the attack, the Waco Tribune-Herald reported in its online edition Wednesday.

Police have issued an arrest warrant charging Lopez with aggravated assault in connection with a previous unrelated incident.

Holt said the women had severe burns and were moved from a Waco hospital to Parkland Memorial Hospital in Dallas. Their conditions were not immediately available.
