Man, armed with assault rifle, fatally shot by ex-girlfriend in Zephyrhills, deputies say

A man who came to his ex-girlfriend's doorstep armed with an assault rifle was shot and killed by that woman Saturday night in Zephyrhills.

According to the Pasco County Sheriff's Office, Frank Harrison, 45, had reportedly made previous threats to his former girlfriend, 38-year-old Alejandrina Guinn.

When Harrison arrived at her home at 5547 Armstrong St. with the rifle, Guinn opened the door and fatally shot him in what appears to be a case of self- defense, officials said. The Sheriff's Office received the call about 10:23 p.m. Saturday.

In 2003, Harrison and Guinn made headlines when 23-year-old Shane Lani Sampson took a fatal shotgun blast to the stomach at the Zephyrhills duplex where Guinn lived at the time. Harrison went to Guinn's home looking for a shotgun to settle an argument with another man, according to Tampa Bay Times coverage of the incident.

While Harrison held the shotgun, it went off, striking Sampson, a husband and father of a girl who was 14 months old at the time.

Authorities picked up Harrison a week later in Hillsborough County on unrelated drug charges. A state prosecutor added a third-degree murder charge.

Although it appeared he had not intended to shoot Sampson, Harrison, a convicted felon, could not legally possess a firearm.

State corrections records show Harrison has served several prison stints since 1991 for charges including robbery with a gun or deadly weapon and cocaine possession. He was most recently released from prison in August.
