Police trying to link 4th murder to suspect in NW Houston warehouse killings

HOUSTON (KTRK) -- An accused mass killer murdered at least one of his victims for money for a white supremacist group, a source close the investigation said Thursday.

Jamie Walter is accused of killing four men. Thursday morning, Walter appeared before a judge on a charge of capital murder for two of the four killings, Monty Kaiser and Donald Fleming. The third man killed was Walter's father, Steve Walter, who was also homeless. Police say all three men were killed with a hammer. Their bodies were found Tuesday night, burned near an abandoned warehouse on Todd Street in northwest Houston.

On Thursday, police said Walter confessed to killing a fourth person.

A source close the investigation said Walter killed that man for $1,000. The source said the hit was ordered by a white supremacist group. According to the source, Walter admitted to leaving the man's body on or near railroad tracks so that the killing looked like an accident.

A source also told ABC-13 Walter killed his father over a family dispute, and after the killing, Walter placed his dad's body in a shopping cart, covered him with a sheet, and rolled him down Todd Street to the abandoned warehouse.

Sources say Walter's wife led investigators to the bodies after she said Walter beat her Tuesday night.

Sources say there may be other victims tied to Jaime Walter.
