( CNN ) -- A Tennessee woman secretly gave birth to twin boys in a toilet in the home she shares with her parents and then smothered the infants and hid their bodies in a bedroom laundry basket , police said Friday . Lindsey Lowe 's father discovered one of the bodies Wednesday morning and called police , Hendersonville Police Lt. Scott Ryan said . `` Someone can give me 100 explanations as to why , but I will never be able to understand this fully , '' he said . Lowe , 25 , was charged with two counts of first-degree murder . She remained jailed Friday pending a Monday appearance before a Sumner County judge . She gave birth to the first baby between 8:30 and 9 p.m. Monday , according to an affidavit filed by police . Lowe , who according to the affidavit confessed to killing her newborns , said she did n't look at either of the babies as she `` placed her hand '' over each child 's mouths to stop them from crying . Lowe told authorities that she knew she was pregnant `` almost the whole time '' but that no one else -- including her family -- was aware , according to the affidavit . It took a `` couple of minutes '' for the first child to die , according to the affidavit , while Lowe said the second baby died more quickly . Both children were males and full-term , weighing about 5 to 6 pounds , the affidavit said . The woman told police she placed the bodies in a laundry basket and covered them with towels to hide them . Her attorney , John Pellegrin , said that his client was `` extremely distraught '' in the two times he 's met with her in jail . Pellegrin said Lowe was `` on suicide watch , '' receiving sedatives from medical personnel at the corrections facility . `` This is an inexplicable situation and extremely sad for everyone involved , '' Pellegrin told HLN 's Jane Velez-Mitchell . She was at work at a dental clinic for children when her father found the bodies , police said . One of her co-workers , Michelle Stainback , told CNN affiliate WTVF that `` we 're all just shocked and saddened . '' `` I 've tried to put myself in that position over and over since last night , '' she said . `` You do n't know what they 're thinking or what they 're going through . '' Ryan admitted that authorities still did n't have all the answers . And Ron Blanton , an assistant district attorney in Sumner County , told HLN 's Velez-Mitchell that the case `` wears on '' those seeking justice in the case . `` It 's a horrible tragedy , a horrible tragedy , '' Blanton said . `` It 's a sad state , a horrific circumstance .
