* At least 10 dead, including gunman and his mother
* Wife and child of deputy sheriff among the victims (Updates death toll, adds quotes, details)
BIRMINGHAM, Ala., March 10 (Reuters) - At least 10 people including the suspected gunman and his mother were killed in a shooting spree and car chase in southern Alabama on Tuesday, authorities said.
The shooter, who was in his mid-30s, killed five people including the wife of a local deputy sheriff and her 3-month-old baby at a mobile home in Samson, according to Wynnton Melton, mayor of nearby Geneva, Alabama.
His other victims included his own mother, two people killed at a convenience store and a man in a pickup truck who died during a car chase as the gunman apparently fired at random, said Melton.
The shooting began in Samson, a small town in the southeastern part of the state and ended after a car chase and gun battle in Geneva, the county seat about 12 miles (20 km) away, according to the FBI and local police.
“Officer Ricky Morgan rammed his car to distract him and was rewarded with a hail of bullets,” said Melton. “One bullet grazed the shoulder of police chief Frankie Lindsey.”
A police officer in Geneva said the gunman “shot at several vehicles on the highway and then he shot at Wal-Mart and Piggly Wiggly,” a grocery store.
A statement from the Alabama Department of Public Safety said state and local law enforcement agencies had responded to “a series of at least four shooting incidents” involving what was believed to be a lone gunman.
The suspect “left at least nine victims dead before he died from a self-inflicted gunshot,” the statement said.
Police said they expected to find more victims. There was no indication of a motive for the spree in which a house was also burned in a nearby county.
Rural southeastern Alabama, which borders Florida, is a largely agricultural area with many low-income families. It relies partly on peanut crops.
Mass shootings have become a feature of life in the United States.
In one of the worst recent incidents, a gunman dressed as Santa Claus killed nine guests at a Christmas Eve party, before taking his own life in Covina, California, a suburb of Los Angeles.
On April 16, 2007, Virginia Tech, a university in Blacksburg, Virginia, became the site of the deadliest rampage in modern U.S. history when a student gunman killed 32 people and himself.
Guns are widely available for purchase in the United States, a country that prides itself on the right to own weapons for self defense and hunting. (Writing by Matthew Bigg; editing by Tom Brown)
