SAN ANTONIO -

An argument between friends on the city's South Side ended in a fiery fashion early Friday when one of them doused the other with gasoline and set him on fire, San Antonio police said.

Police Chief William McManus said the victim was burned 80 to 90 percent of his body.

"The victim's wife was able to transport him after she put the fire out," McManus said.

The suspect also suffered burns. Both men were taken to San Antonio Military Medical Center.

McManus said the men were outside a small office building in the 1900 block of Mauermann Road near Applewhite Road at 6:30 a.m., when the argument erupted.

After the suspect set the victim on fire, he then set fire to the victim's RV, McManus said. The flames spread to the nearby office building.

The susepct then drove off in his pickup truck and and crashed in a deep ditch in a rugged area not far from the original scene.

"The (suspect) called in to report that he had wrecked his truck to some friends or relatives and they alerted the police," McManus said.

Using a helicopter, officers were able to track down the suspect. However, police had to use four-wheelers and other off-road vehicles to reach him.

McManus said it was unclear why the two men, whose names have not been released, were arguing.
