Cops were questioning a police sergeant last night in connection with the murder of his ex-girlfriend – the mother of his two children, officials said.
Sgt. Martin Peters was brought to the 81st Precinct station house in Bedford-Stuyvesant as cops sought information about the death of Juliet Alexander, 29.
Alexander was found shot several times in the back of the head in her apartment on Pulaski Street in Bedford-Stuyvesant.
Cops called to the building at 9:22 a.m. yesterday also found her current boyfriend, Nigel Callender, 32, with wounds to the neck and hand.
He was taken to Kings County Hospital, where he was listed in critical condition. Police said doctors feared he would be paralyzed from his wounds.
He at first told police that Peters, who he’s friends with, was the gunman, investigators said.
Callender was wearing latex gloves when cops arrived and he told them Peters forced him to put on the gloves, investigators said.
He later changed his story, saying it was too dark in the apartment to identify the killer.
Officers said Peters had gone to Alexander’s apartment in the morning to pick up their two children, an 8-year-old boy and a 5-year-old girl, and take them to school.
Peters, who lives alone in Manhattan, was on vacation yesterday and cops finally located him working a second job in Harlem.
Alexander worked as a guard for the Immigration and Naturalization Service in Manhattan.
She carried a gun on the job, but wasn’t supposed to take it home. Cops found the weapon in the apartment, but said it did not appear it had been fired.
Peters became a cop in 1995 and was promoted to sergeant last September, when he was also transferred from the 19th Precinct on the Upper East Side to the Manhattan Courts section.
He is regarded as a hard-working cop who often took on outside security work.
He worked the midnight to 8 a.m. shift and had been studying for a nursing degree.
