SF sheriff’s deputy linked to inmate on gun charges was married to another inmate

A San Francisco sheriff’s deputy arrested last week on federal charges in connection with a boyfriend she met while he was in jail may have had a relationship with another inmate, the San Francisco Examiner has learned.

Court documents show Deputy April Myres had been married to Leonard Colvin, who is standing trial in San Francisco Superior Court for allegedly killing Emmett Byron, 39, in the Tenderloin on July 20, 2013, as revenge for his brother’s death.

Myres’ recent arrest by the FBI, along with former San Francisco inmate Antoine Fowler, who she met while he was in jail, was linked to an alleged insurance fraud scheme. Myres was charged with giving her city-issued gun to Fowler, who was charged with being a felon in possession of a firearm.

Myres met Fowler while she was a jail guard and he was a prisoner. But Myres had also apparently met her ex-husband while he did time in County Jail, according to court records and an inmate who knows Colvin.

“She met Colvin right there in 850 [Bryant St.] on the line, the same way,” said a current County Jail inmate who did not want to be identified for fear of retribution. “[Guards] spend more time with us than they do at home. You’re doing time, too.”

Sheriff’s Department Chief of Staff Eileen Hirst said the department typically does not comment on ongoing investigations or personnel matters.

Since Myres’ arrest, the Sheriff’s Department has put her on administrative leave and condemned the alleged acts.

“The behavior described in the allegations against Ms. Myres falls well below the standard of conduct we and the public expect of peace officers, and it is not reflective of the hard work and dedication of the men and women of the San Francisco Sheriff’s Department,” reads a statement from the department following her arrest.

Myres last worked at San Francisco General Hospital. She has been a deputy since 1996 and allegedly met Fowler when he served time in County Jail from 2010 to 2016 for a conviction related to manufacturing, transporting and selling assault weapons.

Colvin murder testimony

Court documents from the murder trial of Colvin, who is currently in County Jail and whose trial has yet to begin, reveal details of his and Myres’ relationship and the killing that occurred during their time together.

Myres testified in February 2016 at her ex-husband’s preliminary hearing that the pair had been married from February 2012 to September 2013.

“Have you ever had a marital relationship with the defendant Leonard Colvin?” asked Deputy District Attorney John Rowland.

“Yes,” replied Myres, who did not mention how they met.

When asked by Colvin’s defense attorney V. Roy Lefcourt if their relationship started when she was a deputy and he was an inmate, she said it did not.

“No, I was employed, he was not an inmate,” she said.

During their volatile relationship, Colvin threatened one of her sons and pulled a gun on Myres as he choked her, according to her testimony.

Colvin also told her that he was set on avenging his brother, Larry Colvin.

“His brother was shot in the head in Auburn,” Myres said, adding later that “he said that it wasn’t over and he was going to find out who killed his brother … he was going to kill whoever killed his brother.”

On the day of the killing, Colvin borrowed Myres’ Mercedes Benz and did not return until the next day, she said in court.

When police searched her Visitacion Valley home, they found a clip that may have been linked to the murder weapon.

Myres’ 2016 testimony has since been stricken from the record in the Colvin case.
