Gregory Magloire was arrested Thursday on a second-degree murder charge in the death of Josephine Louise Magloire, 68. He was being held without bond Friday at the Turner Guilford Knight Correctional Center.

Deputies responded to the home in the 200 block of Northwest 100th Terrace shortly before 1 p.m. Wednesday after Magloire reported the break-in, the report states. He was not at the residence when deputies arrived but later showed up on a bicycle and led them to a window on the south side of the house.

That window, according to the report, was "visibly boarded up and undisturbed." Magloire told deputies he did not want to go inside and gave them a key, the report states. He also said he knew his room had been ransacked even though he had not been inside, investigators wrote.

Once inside, deputies found Josephine Magloire with apparent head and facial injuries, blood on and near her body, and broken glass with blood nearby, according to the report. Miami-Dade Fire Rescue medics pronounced her dead at the scene.

Deputies detained Gregory Magloire because of what the report described as inconsistencies in his account. During an interview at the sheriff's Homicide Bureau, authorities say, he confessed to repeatedly striking his mother in the head with various blunt objects.

Detectives believe the killing happened the night before he made the burglary call. Deputies seized an item described in the report as a "club/blackjack/brass knuckle" and noted that Magloire appeared to be under the influence of alcohol and drugs.

The arrest report does not state a suspected motive. The investigation is ongoing.
