A police officer says a Hispanic convicted of beheading his common-law wife's three children in 2003 showed no remorse after the killings

Brownsville police Officer John Jones said that John Allen Rubio appeared to be "jovial" in the back of Jones' squad car after Rubio's arrest. Rubio has been convicted of murdering the three children in a windowless downtown apartment. He previously was convicted of killing them but a state appeals court overturned that conviction in 2007 because statements from the children's mother were wrongly allowed as evidence. Prosecutors are seeking another death sentence for Rubio.
