The Mississippi Emergency Management Agency says the state's death toll from violent storms Tuesday and Wednesday is now 11.
Jeff Rent, a spokesman for the agency confirmed the number Wednesday night and said there have been more than 40 injuries.
Damage was reported in 48 counties.
Meanwhile, authorities said a possible tornado heavily damaged much of the town of Smithville in Monroe County.
An updated county-by-county list of confirmed Mississippi fatalities from the storms included one in Choctaw, two in Jasper, three in Kemper, One in Lafayette, one in Pike, one in Smith, one in Webster and one in Yazoo.
The Pike victim was a 3-year-old girl killed Tuesday when a tree fell on her family's home.
Kim Korthuis, a supervisor with the National Park Service at Jeff Busby Park in Choctaw County, Miss., said the 40-year-old man from Covington, La., and his daughter were camping less than 50 feet from the camp's public restrooms, a wood and brick structure that was not damaged.
The tent was sitting just off the main road through the park when the storm came through.
A 125-foot tall sweetgum tree, one of several towering over the campsite, fell onto the tent and killed the man, Korthuis said.
He said the girl survived but was "obviously upset."
Covington, La., police Capt. Jack West identified the victim as Wade Sharp, a lieutenant with the Covington Police Department.
"When the storm came, he threw himself on his daughter" to protect her, West said.
After the tree fell, the girl used her father's cell phone to call the Covington Police Department.
They contacted Mississippi authorities, West said.
Sharp had been with the department for 19 years, first working patrol, then a detail with a drug-detecting dog.
After serving as a shift commander, he worked a special street crimes unit.
At the time of his death, he was an investigator.
"He was a hell of an investigator," West said.
The girl's mother and grandmother picked her up about noon Wednesday.
Other campers were at the park, but no other injuries were reported.

Paul Maier, a volunteer at Jeff Busby Park who helps others on camping trips, said he and his wife slept through the storm in a camper about 100 feet Sharp's campsite.
He said another person brought the girl to stay with him.
He said he went back to the tent to check on the girl's father, he found the man dead. Maier said the girl said she was 9 years old and that she had thought her father had been struck by lightning.
Maier said the way the girl described the situation, he believes her father was trying to get her up and out of the tent to safety.
"She wasn't hurt, just scared and soaking wet," Maier said.
