Stephen Barbee, 37, of Fort Worth, was booked into the Smith County Jail at 1:15 a.m. Bond was set at $2 million.
Lisa Underwood, 34, and her son Jayden were reported missing on Saturday after they failed to appear at a baby shower at Underwood's bagel shop in Fort Worth.
Underwood's sport utility vehicle was discovered abandoned in a creekbed in Denton on Monday. The mother and son remain missing
Early Tuesday morning, acting on a tip, police searched Barbee's home in the 4100 block of Walnut Creek Court at The Hills at Fossil Creek subdivision in North Fort Worth. Investigators removed some material and confirmed they found what they had been looking for, but they would not be more specific.
on edit:
From the radio: "he's talking"..and there was alot of evidence in her truck that they found. Cops are not releasing anything else except they are trying to tie what they found in the truck and at his house all together.
