DNA evidence links a former Dubuque man to a series of home invasions and sexual assaults in 2011 and 2014, according to court documents.

Martel E. Fountain Sr., 29, was arrested at about 6:15 a.m. Tuesday at the Dubuque County Jail on warrants charging four counts of second-degree sexual abuse and four counts of first-degree burglary. He was transferred to the local jail from federal custody.

Each of the eight felony charges is punishable by 25 years in prison upon conviction.

Fountain made an appearance this morning in Iowa District Court of Dubuque County. Associate Judge Robert Richter set his bond at $1 million and set his next hearing for April 5.

Fountain is being represented by the public defender's office. Attorney Les Blair, who is assigned to the case, was unavailable for comment today. 

Court documents state Fountain is accused of forcing his way into the homes of four different women and sexually assaulting them. The Telegraph Herald does not identify possible sexual assault victims.

The first incident occurred at about 3:30 a.m. Aug. 6, 2011, according to court documents. Police responded to a residence on Washington Street and spoke with a woman who said she woke up to her dogs barking. She saw a man who she did not know in her living room who then assaulted and sexually assaulted her. 

The man said he was "going to come back tomorrow" before he fled the residence, documents said. Police determined that the man forced open a window to enter the residence.

A little more than two weeks later -- at about 4:45 a.m. Aug. 22, 2011 -- Dubuque police responded to a home on Jackson Street. A woman there said someone knocked on her door at 4:15 a.m. that morning while shouting, "Police!"

She said a man who she did not know forced his way into the residence. He choked and sexually assaulted her. She told police that the man said, "See you tomorrow" before he left. 

Documents state Dubuque police were called to a home on 22nd Street at about 4 a.m. Nov. 8, 2011. A female resident told police that she was eating cereal when someone knocked on her door. Believing it was a neighbor, she opened the door, and a man she did not know forced his way inside. The man assaulted, choked and sexually assaulted her. 

In March 2012, the staff at the Iowa Division of Criminal Investigations laboratory submitted a report to Dubuque police that said DNA collected after all three sexual assaults came from the same man -- but the man's name was not known. 

The fourth sexual assault occurred at about 4 a.m. May 25, 2014, at a different Jackson Street residence, documents said. A woman reported that a man who she did not know approached her while she was smoking a cigarette outside and pushed her into a garage. She said the man threw her down and choked and sexually assaulted her. 

Tests determined that DNA from that sexual assault came from the same man who committed the three in 2011. 

In March 2018, Fountain was arrested after he was indicted on a federal charge of conspiracy to distribute methamphetamine in the Dubuque area. Upon his arrest, officials took a DNA sample, according to a press release.

Two months later, Dubuque police were notified that the DNA collected from the four sexual assaults matched the DNA from Fountain, according to a press release.

Authorities obtained another DNA swab from Fountain in August 2018, and his DNA again matched the four cases. 

"The probability of finding this profile in a population of unrelated individuals, chosen at random, would be less than 1 out of 100 billion," documents said of Fountain's DNA match.

Fountain's arrest warrants related to the four local cases were issued Nov. 20.

Meanwhile, he was sentenced earlier this month to 12 years, three months in federal prison after pleading guilty to conspiracy to distribute methamphetamine. There is no parole in the federal system.

Federal court documents state that the federal prison term is in addition to a sentence of two years in prison previously imposed for a domestic assault conviction in Iowa District Court for Dubuque County.
