A Jefferson Parish Sheriff’s Office deputy remained in critical condition Tuesday evening after he lost control of his cruiser, sending it careening into a ditch, while responding to a predawn report of a home invasion that turned out to be false.

The deputy, who was identified as Jaron Fountain, 25, lost control of his cruiser on Live Oak Drive near Willswood Drive in Waggaman about 2:35 a.m.

Col. John Fortunato, a Sheriff’s Office spokesman, said Fountain was responding to a report that five people had climbed into an elderly woman’s home on Primrose Lane in Waggaman. The woman told dispatchers that the men refused to leave.

Deputies who arrived at the home later met with the woman, who said the intruders were in an upstairs bedroom, Fortunato said.

A man who lives with the woman told deputies that she has dementia and that there was no one inside the home.

Deputies completed a search of the home and found no signs of forced entry or anyone else inside, Fortunato said.

Fountain was taken to Interim LSU Hospital in New Orleans following the accident.

Fortunato declined to specify the types of injuries Fountain suffered, citing health privacy laws.

Fountain joined the Sheriff’s Office in September 2010 and was initially assigned to the Jefferson Parish Correctional Center.

He graduated from the Sheriff’s Office Academy in August and was assigned to the 3rd District patrol division, which is responsible for most of the unincorporated West Bank of Jefferson Parish.
