(KSLA) - A plane Thursday will join the search of Red River for a woman and her son.
Also, a cadaver dog will ride in one of the boats.
Jennifer Wilson, 53, and 31-year-old Coty Wilson, of the 300 block of Cottage Grove in Benton, have not been seen for almost a week.
The search for them began after motorists spotted her silver Chevrolet Impala abandoned on the top of the Louisiana Highway 2 bridge at Plain Dealing around 6:40 p.m. March 15.
Bossier sheriff's deputies continued their quest Wednesday by putting six watercraft in the river at the former Cash Point boat launch. Among them was a patrol boat from Caddo Pairsh.
