The town had an independent investigator, a former Edgewater police chief, look into the allegations.
9NEWS recently did a story about one detective who is suspected of not investigating cases.
Now, at least one other officer is accused of charging the town for working when he may not have been.
9NEWS spoke with a Weld County official about Sgt. Carl Dwyer's time sheets.
"If you're scheduled to work such and such to such and such, then you need to be on duty," a government official in Weld County familiar with the documents 9NEWS uncovered said.
The person spoke to 9NEWS on condition of anonymity because of the sensitivity of the matter.
"Sgt. Carl Dwyer - he clocked out at 6 [a.m.], but if you go back and you look through dispatch, you can see that he put himself on-call at 3:05 a.m.," the official said. "You can look at all these - he's put himself on-call. He went home at 3 o'clock but wrote himself out at 6 [a.m.]"
According to the Platteville Police Department Policy & Procedure Manual, the police department provides, "uniformed patrol services to the community on a continuous basis, 24 hours a day, seven days a week, 365 days a year."

Based on Dwyer's time sheet for the two weeks of March and April 2010, the sergeant billed Platteville for working eight days, 12 hours per day.
Seven of those days, Dwyer said he worked from 6 p.m. until 6 a.m.
Dwyer checked in with dispatch throughout his shift, detailing where he's going and what he's doing. According to those dispatch logs, Dwyer goes "on-call" or says he's "OC" at about 3 a.m. on six mornings.
In the Platteville Police Manual, there's no such thing as "on-call."
When we asked the town about it, associate and mediator from the law firm representing Platteville Brittany Scantland-Lall told 9NEWS the police chief has discretion when scheduling officers.
Neither Scantland-Lall nor the former police chief, now town manager, Troy Renken, would tell us what "on-call" means or if Renken authorized Dwyer or any other officer to go "on-call" and still bill the city as if they worked those hours.
9NEWS was told the town won't talk about it because of an on-going investigation into these issues.
"I think it's pretty hard to take care of the community when you're home sleeping," the government official with Weld County said. "Who's out patrolling the streets? I know it's 3 a.m. to 6 a.m., supposed to be quiet, but you're also being paid to do a job. You need to be out on the street."
Sgt. Dwyer did not respond a request for comment from 9NEWS.
"Knowing that you're leaving work every day, three hours early, and still charging for those three hours, for seven days - 21 hours - it's a lot of money," the government official said.
Dwyer has been employed in Platteville since August of 2004. He makes $47,511.36 per year, which is $22.84 per hour.
9NEWS contacted three small Colorado police departments that are similar in size to Platteville, asking if it's common for officers to go on-call and be paid for it.
Two of those departments do not allow officers to go on-call during their shift. One said it's possible "once in a while" if the officer has court in the morning. Every department said the officers get paid only for the time worked.
9NEWS has also learned Cpl. Brad Baker, another Platteville Police officer, was interviewed in connection with this investigation.
His attorney Sean T. Olson had no comment.
Baker has been an employee since January of 2006. He makes $43,024.80 per year which is $20.69 per hour.
Scott Smith, a former Platteville police chief who resigned before being convicted of theft, had no comment on the time-sheet issue. Smith was Dwyer's sergeant when Dwyer filed his time sheet.
"If there are discrepancies in the time sheets, the cases should be turned over to the District Attorney's office," Smith said.
The government official with Weld County agrees.
"I think it needs to go to the District Attorney's office," he said. "How many times has it been done before, you get away with something once, how many times have you done it before? I'm wondering how many times this has been done."
9NEWS contacted Platteville Mayor Steve Shafer for a comment on this story. Shafer declined.
The only board-of-trustees member who gave a comment to 9NEWS was Steve Nelson.
Nelson told 9NEWS he was not aware of the police department policy for officers being "on-call."
"In a small town, when we hire people, we do enough of a check on them. After we hire them and get to know them, we may relax our guard a little bit in a small town," Nelson said. "There is a level of trust and familiarity with the police department the big city will never have. We expect different things from our officers. In addition to being police officers, they're counted on dealing with other things too. It's important they're accessible."
Nelson added, "I do have a high level of trust in the town manager [Troy Renken]."
Renken has not responded to 9NEWS request for comment.
9NEWS has learned the independent investigator has already submitted his report to the town board and it is expected to issue a press release or talk about the findings later this week.
