( CNN ) -- Police in San Bernardino , California , released pictures of two suspects in the abduction of a 3-year-old boy who was taken at gunpoint from his home last weekend . Authorities say these men purchased tape from a store and used it 3-year-old Briant Rodriguez 's abduction . Briant Rodriguez has been missing since May 3 , when two Hispanic males armed with handguns burst into the home , tied him up , along with his mother and four siblings . They ransacked the home before leaving with Briant , a small amount of cash and some personal property , San Bernardino County Sheriff 's Public Information Officer Cindy Beavers said . A motive for the abduction is still unclear , and the authorities have not received a demand for ransom , Beavers said . Investigators traced samples of the tape used to tie up the family to a home improvement store where they believe the suspects purchased the tape the Friday before the abduction . The unidentified store 's surveillance camera captured two men who matched the description of the kidnappers given by Briant 's mother , purchasing tape believed to have been used in the abduction , Beavers said . The home improvement store 's exterior surveillance cameras also caught a green Ford Bronco believed to have been used in the abduction , Beavers said . The same car was later seen driving past a convenience store near Briant 's home about three minutes after his mother called police on Sunday to report the abduction , Beavers said . Authorities distributed screen grabs of the footage on Friday showing the suspects and the vehicle in an effort to draw more tips , which have been coming in steadily since an Amber Alert was issued earlier this week . `` You 've got two men that resemble the description given by Briant 's mother , they 're buying tape that matches the tape used to tie them up , then they leave the store in this green Bronco and then on Sunday , just a few minutes before the emergency call for help , the same vehicle is seen leaving the victims ' neighborhood , '' she said . `` Detectives put these two incidents together , and they 're confident that these are the suspects and that was the vehicle used , '' she said . Both suspected kidnappers are Hispanic males -- one 5-feet , 5 inches tall , between the ages of 18 and 20 with a thin build , unknown hair and eye color , last seen wearing a black baseball hat , blue jeans and green T-shirt . The other is 5-foot-10 , around age 24 with a thin build , black boots , a black shirt and a bandanna . Neighboring law enforcement agencies are on alert , and the FBI , Immigration and Customs Enforcement and the U.S. Border Patrol are assisting in the investigation . The FBI and the San Bernardino County Sheriff 's Department have both put up $ 25,000 rewards for Briant 's return . The FBI has also established a Facebook page with the latest information in the case . `` We became involved in the beginning and that 's customary in kidnapping cases because of the potential for cases to go out of state or out of the country , '' FBI Spokeswoman Laura Eimiller said . Despite early speculation that the abduction was related to Mexican cartel violence , both spokeswomen said they were unaware of specific evidence suggesting the family had ties to the drug trade . `` We 've seen an escalation nationwide in south-of-the-border-related kidnappings , whether it be drug cartels exacting revenge or carrying out violence in exchange for drug debts , or in another type of scenario , Americans who do business in Mexico being targeted for ransom , '' Eimiller said . `` Of course that 's being looked at as a scenario here , but we have no conclusive evidence suggesting that 's the case just yet . '' Briant is described in the Amber Alert as a Hispanic male who was last seen wearing a yellow shirt with blue sleeves and blue-striped shorts with two different colors of blue . The boy 's hair is longer than shoulder length .
