The State Fire Marshal is assisting in the investigation of a fatal fire that happened about 9:30 p.m. Thursday on the 500 block of Fifth Street.

John Tiemann who is in his 70s was pronounced dead in the fire.

“He lived alone and he is in his 70s,” said Alice Fire Marshal Patrick Thomas. “We want to find out what happened, more importantly for the family and to prevent from this happening again.”

Firefighters were at the scene until 5:30 a.m. Friday making sure the fire was completely out and handling hot spots. Thomas said they don't suspect any foul play, but will investigate the fire throughout the week. The cause has not been determined.

Tiemann's body was transported to a funeral home and will be taken to the Corpus Christi Medical Examiner's office for an official identification. 

Sandia, Ben Bolt and San Diego volunteer fire departments assisted with the Fifth Street fire which lit up the neighborhood with large flames.

Just a few hours earlier, firefighters battled another fire on the 2800 block of County Road 342. A travel trailer occupied by a man, was destroyed by the fire. Thomas said they notified the Red Cross to assist the man with temporary shelter. No injuries were reported in this fire, Thomas said.

“When a tragedy (fatal) like this happens, we all grieve,” Thomas said. “Our sentiments from the fire department.”
