A timeline emerged yesterday outlining the 5½-hour gap between a fatal Bronx crash involving an allegedly drunken off-duty cop and the time that his blood was drawn to test for alcohol.
Detective Kevin Spell man, 42, was driving on Kingsbridge Avenue in a US Marshal Service-issued Chevy when he struck Al banian immigrant and grandmother Drana Nikac, 67, at 6:37 a.m. Friday.
An hour and a half later, the 23-year veteran allegedly refused to submit to a Breathalyzer test at the scene of the crash and was placed under arrest.
Cops then drove Spellman to the 45th Precinct, where he again refused to take a breath test at 9:47 a.m. — this time on videotape, sources said.
Sources said that investigators at the precinct had to observe the suspect for a half-hour before they could ask him to take the test for a second time.
Three minutes after he refused, he was taken to Jacobi Medical Center so doctors could draw his blood, officials said.
At 11:45 a.m., investigators received a search warrant from a judge and a sample was taken 10 minutes later. The results of the test hadn’t come back as of late yesterday.
Spellman has been charged with vehicular manslaughter, criminally negligent homicide, and DWI.
