The second-in-command at the Episcopal Diocese of Maryland struck and killed a bicyclist and then fled the scene, Baltimore’s top prosecutor said on Friday.

Authorities will issue an arrest warrant for Bishop Suffragan Heather Cook, 58, whose blood-alcohol level tested at 0.22, police said, which is nearly triple the legal limit. She will be charged with vehicular manslaughter, drunken driving, and other counts, according to the Associated Press.

Authorities say Cook was driving on Dec. 27 on a sunny day when the car struck 41-year-old father of two Tom Palermo, who died of head injuries at the hospital later that day. He had been born in Riverton, N.J., and graduated in 1991 from St. Joseph’s Preparatory School.

Cook allegedly left the scene of the crash, but came back about 20 minutes later.

Palermo’s sister-in-law, Alisa Rock, thanked Baltimore State’s Attorney Marilyn Mosby.

She said she was “deeply saddened” to learn of the hit-and-run accident that killed Palermo, and support the decision by the prosecutor to “hold Bishop Heather Cook accountable for her actions to the fullest extent of the law,” according to the report.

Cook, in addition to driving drunk, had allegedly been sending text message when she struck Palermo, according to the Baltimore Sun. She surrendered to police on Friday, with her bail set at $2.5 million. If convicted of manslaughter and leaving the scene, she could be facing 20 years in jail.

Cook had been convicted before, pleading guilty in 2010 on charges of drunken driving. The case has raised numerous questions, including why the Episcopal Diocese raised her to such a high position despite her drunken driving incident, and why authorities took so long after the incident to bring charges against her.

In a statement, the diocese said the organization was “deeply heartbroken over this.”

Cook and Palermo were both heading in the same direction on Roland Avenue when Cook suddenly veered into the bike line, striking Palermo and causing him to be thrown onto the hood of the 2001 Subaru she was driving, colliding with the windshield, according to police.
